It's not the construction of the glyphs that's at issue here, I don't think. The glyphs are drawn to the screen using a separate alpha channel for each component in the pixel, an operation which isn't directly supported by the GL API at present. I don't know what we'd need in the hardware for this to be efficient though; I believe it is possible to do it today using three passes for each string, which seems horrendous until you realize how slow it will be to do the same thing with the CPU. -- [EMAIL PROTECTED]
