// In other words: how did fog ever work, if opaque objects add all of the inscattered light
// between them and the camera, and then the transparencies add even more?
//
// This is our scene initially:
// scene |---is0---------------------------------------> camera
//
// And that's with the transparent object added in between the opaque stuff and the camera:
// scene |---is1---> transparent |---is2---------------> camera
//
// When rendering, we start with the opaque part of the scene and add all the light inscattered between that and the camera: is0.
// Then we add the transparent object. It does two things (let's consider the alpha premultiply version):
// - Dims whatever was behind it (including is0) by OneMinusSrcAlpha
// - Adds light inscattered in front of it (is2), multiplied by Alpha
//
// So all in all we end up with this much inscattered light:
// is0 * OneMinusSrcAlpha + is2 * Alpha
//
// Judging by the diagram, though, the correct amount should be:
// is1 * OneMinusSrcAlpha + is2
//
// Turns out the two expressions are equal - who would've thunk?
// is1 = is0 - is2
// (is0 - is2) * OneMinusSrcAlpha + is2
// is0 * OneMinusSrcAlpha - is2 * (1 - Alpha) + is2
// is0 * OneMinusSrcAlpha - is2 + is2 * Alpha + is2
// is0 * OneMinusSrcAlpha + is2 * Alpha
// I leave figuring out if the fog attenuation is correct as an exercise to the reader ;)
