Fix bug in atlasing. Various other fixes in scheduling aggregate generation.
Add code in texture atlasing to deal with repeated wrapping textures. Also, add code that converts colors in a model into regions within a texture atlas. This color-to-texture conversion code works correctly, but is currently commented out because it increases pressure on texture RAM.
Correctly deal with duplicated faces during simplification.
Various performance improvements to AggregateManager. Add some code that is useful for testing. Add a function for counting triangles in a model, and computing spatial correlation (Moran's I) in a scene.
