/// \class sf::SoundBuffer
/// \ingroup audio
///
/// A sound buffer holds the data of a sound, which is
/// an array of audio samples. A sample is a 16 bits signed integer
/// that defines the amplitude of the sound at a given time.
/// The sound is then reconstituted by playing these samples at
/// a high rate (for example, 44100 samples per second is the
/// standard rate used for playing CDs). In short, audio samples
/// are like texture pixels, and a sf::SoundBuffer is similar to
/// a sf::Texture.
///
/// A sound buffer can be loaded from a file (see loadFromFile()
/// for the complete list of supported formats), from memory, from
/// a custom stream (see sf::InputStream) or directly from an array
/// of samples. It can also be saved back to a file.
///
/// Sound buffers alone are not very useful: they hold the audio data
/// but cannot be played. To do so, you need to use the sf::Sound class,
/// which provides functions to play/pause/stop the sound as well as
/// changing the way it is outputted (volume, pitch, 3D position, ...).
/// This separation allows more flexibility and better performances:
/// indeed a sf::SoundBuffer is a heavy resource, and any operation on it
/// is slow (often too slow for real-time applications). On the other
/// side, a sf::Sound is a lightweight object, which can use the audio data
/// of a sound buffer and change the way it is played without actually
/// modifying that data. Note that it is also possible to bind
/// several sf::Sound instances to the same sf::SoundBuffer.
///
/// It is important to note that the sf::Sound instance doesn't
/// copy the buffer that it uses, it only keeps a reference to it.
/// Thus, a sf::SoundBuffer must not be destructed while it is
/// used by a sf::Sound (i.e. never write a function that
/// uses a local sf::SoundBuffer instance for loading a sound).
///
/// Usage example:
/// \code
/// // Declare a new sound buffer
/// sf::SoundBuffer buffer;
///
/// // Load it from a file
/// if (!buffer.loadFromFile("sound.wav"))
/// {
/// // error...
/// }
///
/// // Create a sound source and bind it to the buffer
/// sf::Sound sound1;
/// sound1.setBuffer(buffer);
///
/// // Play the sound
/// sound1.play();
///
/// // Create another sound source bound to the same buffer
/// sf::Sound sound2;
/// sound2.setBuffer(buffer);
///
/// // Play it with a higher pitch -- the first sound remains unchanged
/// sound2.setPitch(2);
/// sound2.play();
/// \endcode
///
/// \see sf::Sound, sf::SoundBufferRecorder

/// \class sf::SoundRecorder
/// \ingroup audio
///
/// sf::SoundBuffer provides a simple interface to access
/// the audio recording capabilities of the computer
/// (the microphone). As an abstract base class, it only cares
/// about capturing sound samples, the task of making something
/// useful with them is left to the derived class. Note that
/// SFML provides a built-in specialization for saving the
/// captured data to a sound buffer (see sf::SoundBufferRecorder).
///
/// A derived class has only one virtual function to override:
/// \li onProcessSamples provides the new chunks of audio samples while the capture happens
///
/// Moreover, two additional virtual functions can be overridden
/// as well if necessary:
/// \li onStart is called before the capture happens, to perform custom initializations
/// \li onStop is called after the capture ends, to perform custom cleanup
///
/// A derived class can also control the frequency of the onProcessSamples
/// calls, with the setProcessingInterval protected function. The default
/// interval is chosen so that recording thread doesn't consume too much
/// CPU, but it can be changed to a smaller value if you need to process
/// the recorded data in real time, for example.
///
/// The audio capture feature may not be supported or activated
/// on every platform, thus it is recommended to check its
/// availability with the isAvailable() function. If it returns
/// false, then any attempt to use an audio recorder will fail.
///
/// If you have multiple sound input devices connected to your
/// computer (for example: microphone, external soundcard, webcam mic, ...)
/// you can get a list of all available devices through the
/// getAvailableDevices() function. You can then select a device
/// by calling setDevice() with the appropriate device. Otherwise
/// the default capturing device will be used.
///
/// By default the recording is in 16-bit mono. Using the
/// setChannelCount method you can change the number of channels
/// used by the audio capture device to record. Note that you
/// have to decide whether you want to record in mono or stereo
/// before starting the recording.
///
/// It is important to note that the audio capture happens in a
/// separate thread, so that it doesn't block the rest of the
/// program. In particular, the onProcessSamples virtual function
/// (but not onStart and not onStop) will be called
/// from this separate thread. It is important to keep this in
/// mind, because you may have to take care of synchronization
/// issues if you share data between threads.
/// Another thing to bear in mind is that you must call stop()
/// in the destructor of your derived class, so that the recording
/// thread finishes before your object is destroyed.
///
/// Usage example:
/// \code
/// class CustomRecorder : public sf::SoundRecorder
/// {
/// ~CustomRecorder()
/// {
/// // Make sure to stop the recording thread
/// stop();
/// }
///
/// virtual bool onStart() // optional
/// {
/// // Initialize whatever has to be done before the capture starts
/// ...
///
/// // Return true to start playing
/// return true;
/// }
///
/// virtual bool onProcessSamples(const Int16* samples, std::size_t sampleCount)
/// {
/// // Do something with the new chunk of samples (store them, send them, ...)
/// ...

/// return true;
/// }
///
/// virtual void onStop() // optional
/// {
/// // Clean up whatever has to be done after the capture ends
/// ...
/// }

/// // Usage
/// if (CustomRecorder::isAvailable())
/// {
/// CustomRecorder recorder;
///
/// if (!recorder.start())
/// return -1;

/// \class sf::SoundStream
/// \ingroup audio
///
/// Unlike audio buffers (see sf::SoundBuffer), audio streams

/// This behavior allows to play a sound with no loading delay,
/// and keeps the memory consumption very low.
///
/// Sound sources that need to be streamed are usually big files
/// (compressed audio musics that would eat hundreds of MB in memory)
/// or files that would take a lot of time to be received
/// (sounds played over the network).
///
/// sf::SoundStream is a base class that doesn't care about the
/// stream source, which is left to the derived class. SFML provides
/// a built-in specialization for big files (see sf::Music).
/// No network stream source is provided, but you can write your own
/// by combining this class with the network module.
///
/// A derived class has to override two virtual functions:
/// \li onGetData fills a new chunk of audio data to be played
/// \li onSeek changes the current playing position in the source
///
/// It is important to note that each SoundStream is played in its
/// own separate thread, so that the streaming loop doesn't block the
/// rest of the program. In particular, the OnGetData and OnSeek
/// virtual functions may sometimes be called from this separate thread.
/// It is important to keep this in mind, because you may have to take
/// care of synchronization issues if you share data between threads.
///
/// Usage example:
/// \code
/// class CustomStream : public sf::SoundStream
/// {
/// public:
///
/// bool open(const std::string& location)
/// {
/// // Open the source and get audio settings
/// ...
/// unsigned int channelCount = ...;
/// unsigned int sampleRate = ...;
///
/// // Initialize the stream -- important!
/// initialize(channelCount, sampleRate);
/// }
///
/// private:
///
/// virtual bool onGetData(Chunk& data)
/// {
/// // Fill the chunk with audio data from the stream source
/// // (note: must not be empty if you want to continue playing)
/// data.samples = ...;
/// data.sampleCount = ...;
///
/// // Return true to continue playing
/// return true;
/// }
///
/// virtual void onSeek(Uint32 timeOffset)
/// {
/// // Change the current position in the stream source
/// ...
/// }
/// }

/// // Usage
/// CustomStream stream;
/// stream.open("path/to/stream");

/// \ingroup graphics
///
/// sf::BlendMode is a class that represents a blend mode. A blend
/// mode determines how the colors of an object you draw are
/// mixed with the colors that are already in the buffer.
///
/// The class is composed of 6 components, each of which has its
/// own public member variable:
/// \li %Color Source Factor (@ref colorSrcFactor)
/// \li %Color Destination Factor (@ref colorDstFactor)
/// \li %Color Blend Equation (@ref colorEquation)
/// \li Alpha Source Factor (@ref alphaSrcFactor)
/// \li Alpha Destination Factor (@ref alphaDstFactor)
/// \li Alpha Blend Equation (@ref alphaEquation)
///
/// The source factor specifies how the pixel you are drawing contributes
/// to the final color. The destination factor specifies how the pixel
/// already drawn in the buffer contributes to the final color.
///
/// The color channels RGB (red, green, blue; simply referred to as
/// color) and A (alpha; the transparency) can be treated separately. This
/// separation can be useful for specific blend modes, but most often you
/// won't need it and will simply treat the color as a single unit.
///
/// The blend factors and equations correspond to their OpenGL equivalents.
/// In general, the color of the resulting pixel is calculated according
/// to the following formula (\a src is the color of the source pixel, \a dst
/// the color of the destination pixel, the other variables correspond to the
/// public members, with the equations being + or - operators):
/// \code
/// dst.rgb = colorSrcFactor * src.rgb (colorEquation) colorDstFactor * dst.rgb
/// dst.a = alphaSrcFactor * src.a (alphaEquation) alphaDstFactor * dst.a
/// \endcode
/// All factors and colors are represented as floating point numbers between
/// 0 and 1. Where necessary, the result is clamped to fit in that range.
///
/// The most common blending modes are defined as constants
/// in the sf namespace:
///
/// \code
/// sf::BlendMode alphaBlending = sf::BlendAlpha;
/// sf::BlendMode additiveBlending = sf::BlendAdd;
/// sf::BlendMode multiplicativeBlending = sf::BlendMultiply;
/// sf::BlendMode noBlending = sf::BlendNone;
/// \endcode
///
/// In SFML, a blend mode can be specified every time you draw a sf::Drawable
/// object to a render target. It is part of the sf::RenderStates compound
/// that is passed to the member function sf::RenderTarget::draw().
///
/// \see sf::RenderStates, sf::RenderTarget

/// \class sf::Font
/// \ingroup graphics
///
/// Fonts can be loaded from a file, from memory or from a custom
/// stream, and supports the most common types of fonts. See
/// the loadFromFile function for the complete list of supported formats.
///
/// Once it is loaded, a sf::Font instance provides three
/// types of information about the font:
/// \li Global metrics, such as the line spacing
/// \li Per-glyph metrics, such as bounding box or kerning
/// \li Pixel representation of glyphs
///
/// Fonts alone are not very useful: they hold the font data
/// but cannot make anything useful of it. To do so you need to
/// use the sf::Text class, which is able to properly output text
/// with several options such as character size, style, color,
/// position, rotation, etc.
/// This separation allows more flexibility and better performances:
/// indeed a sf::Font is a heavy resource, and any operation on it
/// is slow (often too slow for real-time applications). On the other
/// side, a sf::Text is a lightweight object which can combine the
/// glyphs data and metrics of a sf::Font to display any text on a
/// render target.
/// Note that it is also possible to bind several sf::Text instances
/// to the same sf::Font.
///
/// It is important to note that the sf::Text instance doesn't
/// copy the font that it uses, it only keeps a reference to it.
/// Thus, a sf::Font must not be destructed while it is
/// used by a sf::Text (i.e. never write a function that
/// uses a local sf::Font instance for creating a text).
///
/// Usage example:
/// \code
/// // Declare a new font
/// sf::Font font;
///
/// // Load it from a file
/// if (!font.loadFromFile("arial.ttf"))
/// {
/// // error...
/// }
///
/// // Create a text which uses our font
/// sf::Text text1;
/// text1.setFont(font);
/// text1.setCharacterSize(30);
/// text1.setStyle(sf::Text::Regular);
///
/// // Create another text using the same font, but with different parameters
/// sf::Text text2;
/// text2.setFont(font);
/// text2.setCharacterSize(50);
/// text2.setStyle(sf::Text::Italic);
/// \endcode
///
/// Apart from loading font files, and passing them to instances
/// of sf::Text, you should normally not have to deal directly
/// with this class. However, it may be useful to access the
/// font metrics or rasterized glyphs for advanced usage.
///
/// Note that if the font is a bitmap font, it is not scalable,
/// thus not all requested sizes will be available to use. This
/// needs to be taken into consideration when using sf::Text.
/// If you need to display text of a certain size, make sure the
/// corresponding bitmap font that supports that size is used.
///
/// \see sf::Text

/// To keep things simple, sf::Rect doesn't define

///
/// This means that sf::IntRect(0, 0, 1, 1) and sf::IntRect(1, 1, 1, 1)
/// don't intersect.
///
/// sf::Rect is a template and may be used with any numeric type, but

/// \li sf::Rect<int> is sf::IntRect
/// \li sf::Rect<float> is sf::FloatRect

/// \li applying post-effects to the whole scene with shaders
/// \li creating a sprite from a 3D object rendered with OpenGL
/// \li etc.
///
/// Usage example:
///
/// \code
/// // Create a new render-window
/// sf::RenderWindow window(sf::VideoMode(800, 600), "SFML window");
///
/// // Create a new render-texture
/// sf::RenderTexture texture;
/// if (!texture.create(500, 500))
/// return -1;
///
/// // The main loop
/// while (window.isOpen())
/// {
/// // Event processing
/// // ...
///
/// // Clear the whole texture with red color
/// texture.clear(sf::Color::Red);
///
/// // Draw stuff to the texture
/// texture.draw(sprite); // sprite is a sf::Sprite
/// texture.draw(shape); // shape is a sf::Shape
/// texture.draw(text); // text is a sf::Text
///
/// // We're done drawing to the texture
/// texture.display();
///
/// // Now we start rendering to the window, clear it first

/// // Draw the texture
/// sf::Sprite sprite(texture.getTexture());
/// window.draw(sprite);
///
/// // End the current frame and display its contents on screen
/// window.display();
/// }
/// \endcode
///
/// Like sf::RenderWindow, sf::RenderTexture is still able to render direct

/// \class sf::Shader
/// \ingroup graphics
///
/// Shaders are programs written using a specific language,
/// executed directly by the graphics card and allowing
/// to apply real-time operations to the rendered entities.
///
/// There are three kinds of shaders:
/// \li %Vertex shaders, that process vertices
/// \li Geometry shaders, that process primitives
/// \li Fragment (pixel) shaders, that process pixels
///
/// A sf::Shader can be composed of either a vertex shader
/// alone, a geometry shader alone, a fragment shader alone,
/// or any combination of them. (see the variants of the
/// load functions).
///
/// Shaders are written in GLSL, which is a C-like
/// language dedicated to OpenGL shaders. You'll probably
/// need to learn its basics before writing your own shaders
/// for SFML.
///
/// Like any C/C++ program, a GLSL shader has its own variables
/// called \a uniforms that you can set from your C++ application.
/// sf::Shader handles different types of uniforms:
/// \li scalars: \p float, \p int, \p bool
/// \li vectors (2, 3 or 4 components)
/// \li matrices (3x3 or 4x4)
/// \li samplers (textures)
///
/// Some SFML-specific types can be converted:
/// \li sf::Color as a 4D vector (\p vec4)
/// \li sf::Transform as matrices (\p mat3 or \p mat4)
///
/// Every uniform variable in a shader can be set through one of the
/// setUniform() or setUniformArray() overloads. For example, if you
/// have a shader with the following uniforms:
/// \code
/// uniform float offset;
/// uniform vec3 point;
/// uniform vec4 color;
/// uniform mat4 matrix;
/// uniform sampler2D overlay;
/// uniform sampler2D current;
/// \endcode
/// You can set their values from C++ code as follows, using the types
/// defined in the sf::Glsl namespace:
/// \code
/// shader.setUniform("offset", 2.f);
/// shader.setUniform("point", sf::Vector3f(0.5f, 0.8f, 0.3f));
/// shader.setUniform("color", sf::Glsl::Vec4(color)); // color is a sf::Color
/// shader.setUniform("matrix", sf::Glsl::Mat4(transform)); // transform is a sf::Transform
/// shader.setUniform("overlay", texture); // texture is a sf::Texture
/// shader.setUniform("current", sf::Shader::CurrentTexture);
/// \endcode
///
/// The old setParameter() overloads are deprecated and will be removed in a
/// future version. You should use their setUniform() equivalents instead.
///
/// The special Shader::CurrentTexture argument maps the
/// given \p sampler2D uniform to the current texture of the
/// object being drawn (which cannot be known in advance).
///
/// To apply a shader to a drawable, you must pass it as an
/// additional parameter to the \ref RenderWindow::draw function:
/// \code
/// window.draw(sprite, &shader);
/// \endcode
///
/// ... which is in fact just a shortcut for this:
/// \code
/// sf::RenderStates states;
/// states.shader = &shader;
/// window.draw(sprite, states);
/// \endcode
///
/// In the code above we pass a pointer to the shader, because it may
/// be null (which means "no shader").
///
/// Shaders can be used on any drawable, but some combinations are
/// not interesting. For example, using a vertex shader on a sf::Sprite
/// is limited because there are only 4 vertices, the sprite would
/// have to be subdivided in order to apply wave effects.
/// Another bad example is a fragment shader with sf::Text: the texture
/// of the text is not the actual text that you see on screen, it is
/// a big texture containing all the characters of the font in an
/// arbitrary order; thus, texture lookups on pixels other than the
/// current one may not give you the expected result.
///
/// Shaders can also be used to apply global post-effects to the
/// current contents of the target (like the old sf::PostFx class
/// in SFML 1). This can be done in two different ways:
/// \li draw everything to a sf::RenderTexture, then draw it to
/// the main target using the shader
/// \li draw everything directly to the main target, then use
/// sf::Texture::update(Window&) to copy its contents to a texture
/// and draw it to the main target using the shader
///
/// The first technique is more optimized because it doesn't involve
/// retrieving the target's pixels to system memory, but the
/// second one doesn't impact the rendering process and can be
/// easily inserted anywhere without impacting all the code.
///
/// Like sf::Texture that can be used as a raw OpenGL texture,
/// sf::Shader can also be used directly as a raw shader for
/// custom OpenGL geometry.
/// \code
/// sf::Shader::bind(&shader);
/// ... render OpenGL geometry ...
/// sf::Shader::bind(NULL);
/// \endcode
///
/// \see sf::Glsl

/// \class sf::Texture
/// \ingroup graphics
///
/// sf::Texture stores pixels that can be drawn, with a sprite
/// for example. A texture lives in the graphics card memory,
/// therefore it is very fast to draw a texture to a render target,
/// or copy a render target to a texture (the graphics card can
/// access both directly).
///
/// Being stored in the graphics card memory has some drawbacks.
/// A texture cannot be manipulated as freely as a sf::Image,
/// you need to prepare the pixels first and then upload them
/// to the texture in a single operation (see Texture::update).
///
/// sf::Texture makes it easy to convert from/to sf::Image, but
/// keep in mind that these calls require transfers between
/// the graphics card and the central memory, therefore they are
/// slow operations.
///
/// A texture can be loaded from an image, but also directly
/// from a file/memory/stream. The necessary shortcuts are defined
/// so that you don't need an image first for the most common cases.
/// However, if you want to perform some modifications on the pixels
/// before creating the final texture, you can load your file to a
/// sf::Image, do whatever you need with the pixels, and then call
/// Texture::loadFromImage.
///
/// Since they live in the graphics card memory, the pixels of a texture
/// cannot be accessed without a slow copy first. And they cannot be
/// accessed individually. Therefore, if you need to read the texture's
/// pixels (like for pixel-perfect collisions), it is recommended to
/// store the collision information separately, for example in an array
/// of booleans.
///
/// Like sf::Image, sf::Texture can handle a unique internal
/// representation of pixels, which is RGBA 32 bits. This means
/// that a pixel must be composed of 8 bits red, green, blue and
/// alpha channels -- just like a sf::Color.
///
/// Usage example:
/// \code
/// // This example shows the most common use of sf::Texture:
/// // drawing a sprite
///
/// // Load a texture from a file
/// sf::Texture texture;
/// if (!texture.loadFromFile("texture.png"))
/// return -1;
///
/// // Assign it to a sprite
/// sf::Sprite sprite;
/// sprite.setTexture(texture);
///
/// // Draw the textured sprite
/// window.draw(sprite);
/// \endcode
///
/// \code
/// // This example shows another common use of sf::Texture:
/// // streaming real-time data, like video frames
///
/// // Create an empty texture
/// sf::Texture texture;
/// if (!texture.create(640, 480))
/// return -1;
///
/// // Create a sprite that will display the texture
/// sf::Sprite sprite(texture);
///
/// while (...) // the main loop
/// {
/// ...
///
/// // update the texture
/// sf::Uint8* pixels = ...; // get a fresh chunk of pixels (the next frame of a movie, for example)
/// texture.update(pixels);
///
/// // draw it
/// window.draw(sprite);
///
/// ...
/// }
///
/// \endcode
///
/// Like sf::Shader that can be used as a raw OpenGL shader,
/// sf::Texture can also be used directly as a raw texture for
/// custom OpenGL geometry.
/// \code
/// sf::Texture::bind(&texture);
/// ... render OpenGL geometry ...
/// sf::Texture::bind(NULL);
/// \endcode

/// \class sf::Transformable
/// \ingroup graphics
///
/// This class is provided for convenience, on top of sf::Transform.
///
/// sf::Transform, as a low-level class, offers a great level of
/// flexibility but it is not always convenient to manage. Indeed,
/// one can easily combine any kind of operation, such as a translation
/// followed by a rotation followed by a scaling, but once the result
/// transform is built, there's no way to go backward and, let's say,
/// change only the rotation without modifying the translation and scaling.
/// The entire transform must be recomputed, which means that you
/// need to retrieve the initial translation and scale factors as
/// well, and combine them the same way you did before updating the
/// rotation. This is a tedious operation, and it requires to store
/// all the individual components of the final transform.
///
/// That's exactly what sf::Transformable was written for: it hides
/// these variables and the composed transform behind an easy to use
/// interface. You can set or get any of the individual components
/// without worrying about the others. It also provides the composed
/// transform (as a sf::Transform), and keeps it up-to-date.
///
/// In addition to the position, rotation and scale, sf::Transformable
/// provides an "origin" component, which represents the local origin
/// of the three other components. Let's take an example with a 10x10
/// pixels sprite. By default, the sprite is positioned/rotated/scaled
/// relatively to its top-left corner, because it is the local point
/// (0, 0). But if we change the origin to be (5, 5), the sprite will
/// be positioned/rotated/scaled around its center instead. And if
/// we set the origin to (10, 10), it will be transformed around its
/// bottom-right corner.
///
/// To keep the sf::Transformable class simple, there's only one
/// origin for all the components. You cannot position the sprite
/// relatively to its top-left corner while rotating it around its
/// center, for example. To do such things, use sf::Transform directly.
///
/// sf::Transformable can be used as a base class. It is often
/// combined with sf::Drawable -- that's what SFML's sprites,
/// texts and shapes do.
/// \code
/// class MyEntity : public sf::Transformable, public sf::Drawable
/// {
/// virtual void draw(sf::RenderTarget& target, sf::RenderStates states) const
/// {
/// states.transform *= getTransform();
/// target.draw(..., states);
/// }
/// };
///
/// MyEntity entity;
/// entity.setPosition(10, 20);
/// entity.setRotation(45);
/// window.draw(entity);
/// \endcode
///
/// It can also be used as a member, if you don't want to use
/// its API directly (because you don't need all its functions,
/// or you have different naming conventions for example).
/// \code
/// class MyEntity
/// {
/// public:
/// void SetPosition(const MyVector& v)
/// {
/// myTransform.setPosition(v.x(), v.y());
/// }
///
/// void Draw(sf::RenderTarget& target) const
/// {
/// target.draw(..., myTransform.getTransform());
/// }
///
/// private:
/// sf::Transformable myTransform;
/// };
/// \endcode
///
/// A note on coordinates and undistorted rendering: \n
/// By default, SFML (or more exactly, OpenGL) may interpolate drawable objects
/// such as sprites or texts when rendering. While this allows transitions
/// like slow movements or rotations to appear smoothly, it can lead to
/// unwanted results in some cases, for example blurred or distorted objects.
/// In order to render a sf::Drawable object pixel-perfectly, make sure
/// the involved coordinates allow a 1:1 mapping of pixels in the window
/// to texels (pixels in the texture). More specifically, this means:
/// * The object's position, origin and scale have no fractional part
/// * The object's and the view's rotation are a multiple of 90 degrees
/// * The view's center and size have no fractional part
///
/// \see sf::Transform

///
/// In situations where a large amount of vertex data would
/// have to be transferred from system memory to graphics memory
/// every frame, using sf::VertexBuffer can help. By using a
/// sf::VertexBuffer, data that has not been changed between frames
/// does not have to be re-transferred from system to graphics
/// memory as would be the case with sf::VertexArray. If data transfer
/// is a bottleneck, this can lead to performance gains.
///
/// Using sf::VertexBuffer, the user also has the ability to only modify
/// a portion of the buffer in graphics memory. This way, a large buffer
/// can be allocated at the start of the application and only the
/// applicable portions of it need to be updated during the course of
/// the application. This allows the user to take full control of data
/// transfers between system and graphics memory if they need to.
///
/// In special cases, the user can make use of multiple threads to update
/// vertex data in multiple distinct regions of the buffer simultaneously.
/// This might make sense when e.g. the position of multiple objects has to
/// be recalculated very frequently. The computation load can be spread
/// across multiple threads as long as there are no other data dependencies.
///
/// Simultaneous updates to the vertex buffer are not guaranteed to be
/// carried out by the driver in any specific order. Updating the same
/// region of the buffer from multiple threads will not cause undefined
/// behaviour, however the final state of the buffer will be unpredictable.
///
/// Simultaneous updates of distinct non-overlapping regions of the buffer
/// are also not guaranteed to complete in a specific order. However, in
/// this case the user can make sure to synchronize the writer threads at
/// well-defined points in their code. The driver will make sure that all
/// pending data transfers complete before the vertex buffer is sourced
/// by the rendering pipeline.
///
/// It inherits sf::Drawable, but unlike other drawables it
/// is not transformable.
///
/// Example:
/// \code
/// sf::Vertex vertices[15];
/// ...
/// sf::VertexBuffer triangles(sf::Triangles);
/// triangles.create(15);
/// triangles.update(vertices);
/// ...
/// window.draw(triangles);

/// \class sf::Ftp
/// \ingroup network
///
/// sf::Ftp is a very simple FTP client that allows you
/// to communicate with a FTP server. The FTP protocol allows
/// you to manipulate a remote file system (list files,
/// upload, download, create, remove, ...).
///
/// Using the FTP client consists of 4 parts:
/// \li Connecting to the FTP server
/// \li Logging in (either as a registered user or anonymously)
/// \li Sending commands to the server
/// \li Disconnecting (this part can be done implicitly by the destructor)
///
/// Every command returns a FTP response, which contains the
/// status code as well as a message from the server. Some
/// commands such as getWorkingDirectory() and getDirectoryListing()
/// return additional data, and use a class derived from
/// sf::Ftp::Response to provide this data. The most often used
/// commands are directly provided as member functions, but it is
/// also possible to use specific commands with the sendCommand() function.
///
/// Note that response statuses >= 1000 are not part of the FTP standard,
/// they are generated by SFML when an internal error occurs.
///
/// All commands, especially upload and download, may take some
/// time to complete. This is important to know if you don't want
/// to block your application while the server is completing
/// the task.
///
/// Usage example:
/// \code
/// // Create a new FTP client
/// sf::Ftp ftp;
///
/// // Connect to the server
/// sf::Ftp::Response response = ftp.connect("ftp://ftp.myserver.com");
/// if (response.isOk())
/// std::cout << "Connected" << std::endl;
///
/// // Log in
/// response = ftp.login("laurent", "dF6Zm89D");
/// if (response.isOk())
/// std::cout << "Logged in" << std::endl;
///
/// // Print the working directory
/// sf::Ftp::DirectoryResponse directory = ftp.getWorkingDirectory();
/// if (directory.isOk())
/// std::cout << "Working directory: " << directory.getDirectory() << std::endl;
///
/// // Create a new directory
/// response = ftp.createDirectory("files");
/// if (response.isOk())
/// std::cout << "Created new directory" << std::endl;
///
/// // Upload a file to this new directory
/// response = ftp.upload("local-path/file.txt", "files", sf::Ftp::Ascii);
/// if (response.isOk())
/// std::cout << "File uploaded" << std::endl;
///
/// // Send specific commands (here: FEAT to list supported FTP features)
/// response = ftp.sendCommand("FEAT");
/// if (response.isOk())
/// std::cout << "Feature list:\n" << response.getMessage() << std::endl;
///
/// // Disconnect from the server (optional)
/// ftp.disconnect();
/// \endcode

/// \class sf::SocketSelector
/// \ingroup network
///
/// Socket selectors provide a way to wait until some data is
/// available on a set of sockets, instead of just one. This
/// is convenient when you have multiple sockets that may
/// possibly receive data, but you don't know which one will
/// be ready first. In particular, it avoids to use a thread
/// for each socket; with selectors, a single thread can handle
/// all the sockets.
///
/// All types of sockets can be used in a selector:
/// \li sf::TcpListener
/// \li sf::TcpSocket
/// \li sf::UdpSocket
///
/// A selector doesn't store its own copies of the sockets
/// (socket classes are not copyable anyway), it simply keeps
/// a reference to the original sockets that you pass to the
/// "add" function. Therefore, you can't use the selector as a
/// socket container, you must store them outside and make sure
/// that they are alive as long as they are used in the selector.
///
/// Using a selector is simple:
/// \li populate the selector with all the sockets that you want to observe
/// \li make it wait until there is data available on any of the sockets
/// \li test each socket to find out which ones are ready
///
/// Usage example:
/// \code
/// // Create a socket to listen to new connections
/// sf::TcpListener listener;
/// listener.listen(55001);
///
/// // Create a list to store the future clients
/// std::list<sf::TcpSocket*> clients;
///
/// // Create a selector
/// sf::SocketSelector selector;
///
/// // Add the listener to the selector
/// selector.add(listener);
///
/// // Endless loop that waits for new connections
/// while (running)
/// {
/// // Make the selector wait for data on any socket
/// if (selector.wait())
/// {
/// // Test the listener
/// if (selector.isReady(listener))
/// {
/// // The listener is ready: there is a pending connection
/// sf::TcpSocket* client = new sf::TcpSocket;
/// if (listener.accept(*client) == sf::Socket::Done)
/// {
/// // Add the new client to the clients list
/// clients.push_back(client);
///
/// // Add the new client to the selector so that we will
/// // be notified when he sends something
/// selector.add(*client);
/// }
/// else
/// {
/// // Error, we won't get a new connection, delete the socket
/// delete client;
/// }
/// }
/// else
/// {
/// // The listener socket is not ready, test all other sockets (the clients)
/// for (std::list<sf::TcpSocket*>::iterator it = clients.begin(); it != clients.end(); ++it)
/// {

/// \class sf::TcpSocket
/// \ingroup network
///
/// TCP is a connected protocol, which means that a TCP
/// socket can only communicate with the host it is connected
/// to. It can't send or receive anything if it is not connected.
///
/// The TCP protocol is reliable but adds a slight overhead.
/// It ensures that your data will always be received in order
/// and without errors (no data corrupted, lost or duplicated).
///
/// When a socket is connected to a remote host, you can
/// retrieve informations about this host with the
/// getRemoteAddress and getRemotePort functions. You can
/// also get the local port to which the socket is bound
/// (which is automatically chosen when the socket is connected),
/// with the getLocalPort function.
///
/// Sending and receiving data can use either the low-level
/// or the high-level functions. The low-level functions
/// process a raw sequence of bytes, and cannot ensure that
/// one call to Send will exactly match one call to Receive
/// at the other end of the socket.
///
/// The high-level interface uses packets (see sf::Packet),
/// which are easier to use and provide more safety regarding
/// the data that is exchanged. You can look at the sf::Packet
/// class to get more details about how they work.
///
/// The socket is automatically disconnected when it is destroyed,
/// but if you want to explicitly close the connection while
/// the socket instance is still alive, you can call disconnect.
///
/// Usage example:
/// \code
/// // ----- The client -----
///
/// // Create a socket and connect it to 192.168.1.50 on port 55001
/// sf::TcpSocket socket;
/// socket.connect("192.168.1.50", 55001);
///
/// // Send a message to the connected host
/// std::string message = "Hi, I am a client";
/// socket.send(message.c_str(), message.size() + 1);
///
/// // Receive an answer from the server
/// char buffer[1024];
/// std::size_t received = 0;
/// socket.receive(buffer, sizeof(buffer), received);
/// std::cout << "The server said: " << buffer << std::endl;
///
/// // ----- The server -----
///
/// // Create a listener to wait for incoming connections on port 55001
/// sf::TcpListener listener;
/// listener.listen(55001);
///
/// // Wait for a connection
/// sf::TcpSocket socket;
/// listener.accept(socket);
/// std::cout << "New client connected: " << socket.getRemoteAddress() << std::endl;
///
/// // Receive a message from the client
/// char buffer[1024];
/// std::size_t received = 0;
/// socket.receive(buffer, sizeof(buffer), received);

///

/// \class sf::UdpSocket
/// \ingroup network
///
/// A UDP socket is a connectionless socket. Instead of
/// connecting once to a remote host, like TCP sockets,
/// it can send to and receive from any host at any time.
///
/// It is a datagram protocol: bounded blocks of data (datagrams)
/// are transfered over the network rather than a continuous
/// stream of data (TCP). Therefore, one call to send will always
/// match one call to receive (if the datagram is not lost),
/// with the same data that was sent.
///
/// The UDP protocol is lightweight but unreliable. Unreliable
/// means that datagrams may be duplicated, be lost or
/// arrive reordered. However, if a datagram arrives, its
/// data is guaranteed to be valid.
///
/// UDP is generally used for real-time communication
/// (audio or video streaming, real-time games, etc.) where
/// speed is crucial and lost data doesn't matter much.
///
/// Sending and receiving data can use either the low-level
/// or the high-level functions. The low-level functions
/// process a raw sequence of bytes, whereas the high-level
/// interface uses packets (see sf::Packet), which are easier
/// to use and provide more safety regarding the data that is
/// exchanged. You can look at the sf::Packet class to get
/// more details about how they work.
///
/// It is important to note that UdpSocket is unable to send
/// datagrams bigger than MaxDatagramSize. In this case, it
/// returns an error and doesn't send anything. This applies
/// to both raw data and packets. Indeed, even packets are
/// unable to split and recompose data, due to the unreliability
/// of the protocol (dropped, mixed or duplicated datagrams may
/// lead to a big mess when trying to recompose a packet).
///
/// If the socket is bound to a port, it is automatically
/// unbound from it when the socket is destroyed. However,
/// you can unbind the socket explicitly with the Unbind
/// function if necessary, to stop receiving messages or
/// make the port available for other sockets.
///
/// Usage example:
/// \code
/// // ----- The client -----
///
/// // Create a socket and bind it to the port 55001
/// sf::UdpSocket socket;
/// socket.bind(55001);
///
/// // Send a message to 192.168.1.50 on port 55002
/// std::string message = "Hi, I am " + sf::IpAddress::getLocalAddress().toString();
/// socket.send(message.c_str(), message.size() + 1, "192.168.1.50", 55002);

/// Because the mutex is not explicitly unlocked in the code,

/// Mutex stands for "MUTual EXclusion". A mutex is a
/// synchronization object, used when multiple threads are involved.
///
/// When you want to protect a part of the code from being accessed
/// simultaneously by multiple threads, you typically use a
/// mutex. When a thread is locked by a mutex, any other thread
/// trying to lock it will be blocked until the mutex is released
/// by the thread that locked it. This way, you can allow only
/// one thread at a time to access a critical region of your code.
///
/// Usage example:
/// \code
/// Database database; // this is a critical resource that needs some protection
/// sf::Mutex mutex;
///
/// void thread1()
/// {
/// mutex.lock(); // this call will block the thread if the mutex is already locked by thread2
/// database.write(...);
/// mutex.unlock(); // if thread2 was waiting, it will now be unblocked
/// }
///
/// void thread2()
/// {
/// mutex.lock(); // this call will block the thread if the mutex is already locked by thread1
/// database.write(...);
/// mutex.unlock(); // if thread1 was waiting, it will now be unblocked
/// }
/// \endcode
///
/// Be very careful with mutexes. A bad usage can lead to bad problems,
/// like deadlocks (two threads are waiting for each other and the
/// application is globally stuck).
///
/// To make the usage of mutexes more robust, particularly in
/// environments where exceptions can be thrown, you should
/// use the helper class sf::Lock to lock/unlock mutexes.
///
/// SFML mutexes are recursive, which means that you can lock
/// a mutex multiple times in the same thread without creating
/// a deadlock. In this case, the first call to lock() behaves
/// as usual, and the following ones have no effect.
/// However, you must call unlock() exactly as many times as you
/// called lock(). If you don't, the mutex won't be released.

///
/// It automatically handles conversions from/to ANSI and

/// sf::String.
///
/// \code
/// sf::String s;
///
/// std::string s1 = s; // automatically converted to ANSI string
/// std::wstring s2 = s; // automatically converted to wide string
/// s = "hello"; // automatically converted from ANSI string
/// s = L"hello"; // automatically converted from wide string
/// s += 'a'; // automatically converted from ANSI string
/// s += L'a'; // automatically converted from wide string
/// \endcode
///
/// Conversions involving ANSI strings use the default user locale. However
/// it is possible to use a custom locale if necessary:
/// \code
/// std::locale locale;
/// sf::String s;
/// ...
/// std::string s1 = s.toAnsiString(locale);
/// s = sf::String("hello", locale);
/// \endcode
///
/// sf::String defines the most important functions of the
/// standard std::string class: removing, random access, iterating,
/// appending, comparing, etc. However it is a simple class
/// provided for convenience, and you may have to consider using
/// a more optimized class if your program requires complex string
/// handling. The automatic conversion functions will then take
/// care of converting your string to sf::String whenever SFML
/// requires it.
///
/// Please note that SFML also defines a low-level, generic
/// interface for Unicode handling, see the sf::Utf classes.

///
/// The template parameter T is the type of the coordinates. It

///
/// You generally don't have to care about the templated form (sf::Vector3<T>),

/// \li sf::Vector3<int> is sf::Vector3i

/// The sf::Vector3 class has a small and simple interface, its x and y members
/// can be accessed directly (there are no accessors like setX(), getX()) and it
/// contains no mathematical function like dot product, cross product, length, etc.
///
/// Usage example:
/// \code
/// sf::Vector3f v1(16.5f, 24.f, -8.2f);
/// v1.x = 18.2f;
/// float y = v1.y;
/// float z = v1.z;

/// sf::Vector3f v2 = v1 * 5.f;
/// sf::Vector3f v3;
/// v3 = v1 + v2;
///
/// bool different = (v2 != v3);
/// \endcode

/// \ingroup window
///
/// ContextSettings allows to define several advanced settings
/// of the OpenGL context attached to a window. All these
/// settings with the exception of the compatibility flag
/// and anti-aliasing level have no impact on the regular
/// SFML rendering (graphics module), so you may need to use
/// this structure only if you're using SFML as a windowing
/// system for custom OpenGL rendering.
///
/// The depthBits and stencilBits members define the number
/// of bits per pixel requested for the (respectively) depth
/// and stencil buffers.
///
/// antialiasingLevel represents the requested number of
/// multisampling levels for anti-aliasing.
///
/// majorVersion and minorVersion define the version of the
/// OpenGL context that you want. Only versions greater or
/// equal to 3.0 are relevant; versions lesser than 3.0 are
/// all handled the same way (i.e. you can use any version
/// < 3.0 if you don't want an OpenGL 3 context).
///
/// When requesting a context with a version greater or equal
/// to 3.2, you have the option of specifying whether the
/// context should follow the core or compatibility profile
/// of all newer (>= 3.2) OpenGL specifications. For versions
/// 3.0 and 3.1 there is only the core profile. By default
/// a compatibility context is created. You only need to specify
/// the core flag if you want a core profile context to use with
/// your own OpenGL rendering.
/// <b>Warning: The graphics module will not function if you
/// request a core profile context. Make sure the attributes are
/// set to Default if you want to use the graphics module.</b>
///
/// Setting the debug attribute flag will request a context with
/// additional debugging features enabled. Depending on the
/// system, this might be required for advanced OpenGL debugging.
/// OpenGL debugging is disabled by default.
///
/// <b>Special Note for OS X:</b>
/// Apple only supports choosing between either a legacy context
/// (OpenGL 2.1) or a core context (OpenGL version depends on the
/// operating system version but is at least 3.2). Compatibility
/// contexts are not supported. Further information is available on the
/// <a href="https://developer.apple.com/opengl/capabilities/index.html">
/// OpenGL Capabilities Tables</a> page. OS X also currently does
/// not support debug contexts.
///
/// Please note that these values are only a hint.
/// No failure will be reported if one or more of these values
/// are not supported by the system; instead, SFML will try to
/// find the closest valid match. You can then retrieve the
/// settings that the window actually used to create its context,
/// with Window::getSettings().
