* Cleaning up the conversion code to avoid a per-face material conversion. Materials are now stored in buckets and only converted if a new material is found. This replaces some of Campbell's earlier work on the subject. His work wasn't as thorough, but it was much safer for a release. * Shaders are only compiled for LibLoaded materials once. Before they could be compiled twice, which could really slow things down. * Refactoring the rasterizer code to use a strategy design pattern to handle different geometry rendering methods such as immediate mode, vertex arrays and vertex buffer objects. VBOs are added, but they will be disabled in a following commit since they are still slower than vertex arrays with display lists. However, VBOs are still useful for mobile, so it's good to keep them around. * Better multi-uv support. The BGE should now be able to handle more than two UV layers, which should help it better match the viewport.
