For clarity sake, the batch cache now uses exclusively per Loop attributes. While this is a bit of a waste of VRAM (for the few case where per vert attribs are enough) it reduces the complexity and amount of overall VBO to update in general situations. This patch also makes the VertexBuffers filling multithreaded. This make the update of dense meshes a bit faster. The main bottleneck is the IndexBuffers update which cannot be multithreaded efficiently (have to increment a counter and/or do a final sorting pass). We introduce the concept of "extract" functions/step. All extract functions are executed in one thread each and if possible, using multiple thread for looping over all elements.
