OpenGL Renderer: Clipping Bug

[Stefan H. <st...@to...>]

The following problem is related to nearly all renderers (exept for 
Quesa Interactive).

The attached model contains three sheared boxes. Two of them are 
semitranparent. When I rotate the model, all the boxes disappear 
sometimes if the camera is near the model. The nearer the camera the 
more problems.

The problem has been introduced between 2009-05-14 and 2009-12-20.
