RenderFastPathTriMesh: Triangle strip problem

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

The combination of kQ3FillStyleEdges and kQ3BackfacingStyleBoth/Flip 
produces for large trimeshes (see kMinTrianglesToCache) junk lines 
when kQ3RendererPropertyAutomaticTriangleStrips is on and VBOs are 
used.

Removing QORenderer::Renderer::RenderFastPathTriMesh line 1010f 
(GetCachedTriangleStrip) temporarily "solves" the problem.

The error occurs with Quesa OpenGL when kQ3FillStyleEdges is on and 
with Quesa Wireframe and Hiddenline (Wireframe and  Hiddenline are 
using glPolygonMode( GL_FRONT_AND_BACK, GL_LINE )).

The Interactive renderer has its own backface culling: here all is ok.
