"WebSince OpenGL is designed for rendering, it is natual that it provides extensive vector support. Both geometry (XYZW) and color (RGBA) require vec4, and it is easy to perform operations on vectors (e.g. addition, subtraction, dot product, …). Therefore, a natual optimization that one can think of is to utilize all the color channels in a texture. " - Opengl xyzw
