Grey Idea for GL 5.0

[DanKarron at UCBVAX.BERKELEY.EDU]

Here is my nomination for a gl color vector call for use
color blind medical imaging types. All of my data is gray scale
data, but I want to use vertex color calls, which all expect rgb or
rgba data. Since I don't want to pad all my pixels with redundant rgb
data, and copying the pixel value data twice to make a color vector is
also redundant, I would like to see a fast vertex color call that takes
only 1 value, and generates a grey value, say from 0->255 (or more, but that
is another issue). Instead of copying bytes, such a call would just
tie all the color dac's together for fast grey pixel rendering.

Cheers!
