Detailed Description

+A class used to render instances sorted by MeshGeom first, then per material, where possible. +

+This allow optimisation because less renderState swapping are needed. WARNING: if you add MeshGeom to 2 different CMeshBlockManager at same times, it won't work, and will certainly crashes (not checked/assert). +

+NB VBHeap part works, even if no User interface use it. It don't give greate performance Add, but will may be used. +
