Summary

0025463: Visualization - MeshVS_ElementalColorPrsBuilder produces inefficient structures for elements with unique colors

Description

MeshVS_ElementalColorPrsBuilder group mesh Elements with the same color, however this optimization become overkill when unique color is assigned for each Element.

For this case specialized GLSL program using gl_PrimitiveID and TBO with colors or texture would be preferred solution, and simple array with per-vertex color assigned will be fallback solution.
