...ee there is 215 lines (from 66 to 280) of valgrind--mmt that I do not know from where is it coming.

Help, please.*/ /* This I guess is mesa stuff... */ glMatrixMode(GL_PROJECTION); glLoadIdentity(); glOrtho(0, 300, 0, 300, -1, 1); glMatrixMode(GL_MODELVIEW); /*Here another question. Does glBegin end up calling a driver code like BEGIN_NV04(...) that instructs the card to get the next 3 floats for color more 3 for the first vertex and another 3 for the other?...
