I have a problem I cannot solve.
In my programme I put a luminance/alpha bitmap
on the color-buffer. The result is a white image
(a letter/digit). I would like to be able to set
the color, but my first attempts very unsuccessful.
worked fine, but soooo sloooooow. Is there another
technique to set the color? Low level conversion
of the luminance_alpha bitmap to RGBA is not an
An option would be the use of tectures and GL_MODULATE, but I would like to avoid textures for this.
