// Blend Add Shader (as used in Diablo 3)
// Uses the alpha channel to determine if the pixel needs to be blended additively or by transparency.
// Is a good way prevent the additive buildup that makes a scene with a lot of particle effects white and unreadable while still having some particle texture features.
