Randy Heit bf31d66d31 Use a better packing algorithm for the texture atlases 
- The old algorithm is something I threw together that produced decent,
  but not spectacular results since it had a tendency to waste space by
  forcing everything onto "shelves".
  The new packer is the Skyline-MinWaste-WasteMap-BestFirstFit algorithm
  described by Jukka Jylanki in his paper *A Thousand Ways to Pack the Bin - A
  Practical Approach to Two-Dimensional Rectangle Bin Packing*, which can
  currently be read at http://clb.demon.fi/files/RectangleBinPack.pdf
  This is minus the optimization to rotate rectangles to make better fits.
