I don't know PixelBufferObject, but I think that my approach is different.
It's very simple and just renders the trapezoids given to
There are no sofisticated things and no FBOs or PBuffers and such, but this
way it should work with any given OpenGL context (WGL, GLX, AGL, FBO, mesa
offscreen buffer, etc.).
Operator support is still missing as I didn't need them yet, but I hope that
this shouldn't be too difficult to implement using OpenGL logical operators.
