Sometimes there is a need to flip along the axes, as in jzopengl_win32. I suggest to see if it's possible to delegate it to the 2D API (StretchBlt), while indicating the flip with, for example negative dimention on the corresponding axis, e.g.
glpixels 10 10 2 _2 1 0 0 1 will show a flipped vertically icon: . X X . Same for glqpixels, glpixelsx. This is distantly similar to how Cut (;.) works. __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
