  1. Implement better scan and split strategies for the atlas allocator, and 

    use as large of a texture as the hardware allows.

The texture atlas allocator now uses the Best Area Fit and Max/Min Area
Split Rules to make decisions. These were the optimum strategies for the
guillotine algorithm in "A Thousand Ways to Pack the Bin":

Seems to result in much decreased texture atlas fragmentation.
