Imagine a planar-(quad-MESH) -> all vertices of the mesh
lie on same plane. -> in this case there is no difference
in which order quads are drawn -> but same errors.

ordering-problems have the effect that primitives nearer to
viewpoint are overdrawn with primitives behind them.
in my case, if quads are not drawn, the black background appears.
-> because they are not drawn (not overdrawn) 

im sure the errors are caused due to the bug described before.

But ive found something to optimise -> my orderingtable-length
was to high.
