[Bf-committers] Really strange...no rendering at all and materials lost in space

[Ton Roosendaal]

Hi,

Urm... what I learned is that the glDrawPixels function doesnt allow  
drawing rects when the first pixel (left) is outside of the clipping  
area. This is a builtin limitation of opengl.
There is code in Blender to bypass that, just didnt look into that  
yet... the preview render code is already more than messy enough.
