I also thought about this possibility while considering to write my own gui library. Btw, would it be more effective to use OpenGL feedback mode, i.e. when it's GPU who calculates your screen and you are getting the final result not on screen but in memory. But I don't know, would it be faster, because AGP bus works very slowly in sending data back from the accelerator. But who knows, maybe it's still faster than using CPU for rendering? Did you consider such possibility? This would be meaning that you don't have to implement line drawing algorithms etc.

It isn't slow just on startup, it's permanently slow. But isn't drawing that font labels nothing more than drawing texture quads, if you say they all are precomputed? Also I wouldn't say there are tons of text labels, probably less than 50.

I'll be waiting! P.S. Can ngl&nui be compiled on Visual C++ 6.0 without any updates? I just don't have new version or any updates at hand to test it on windows. I remember I tried to compile ngl-bundle, but it gave me errors.
