With the advent of programmable shaders and render-to-texture capabilities these legacy formats carry some historical artifacts which are no longer useful. For example, when sampling from such textures, the luminance values are replicated across the color components. This is no longer necessary with programmable shaders. It is also desirable to be able to render to one- and two-component format textures using capabilities such as framebuffer objects (FBO), but rendering to L/LA formats is under-specified (specifically how to map R/G/B/A values to L/A texture channels). This extension adds new base internal formats for one-component RED and two-component RG (red green) textures as well as sized RED and RG internal formats for renderbuffers. The RED and RG texture formats can be used for both texturing and rendering into with framebuffer objects.
