TextureTileArray Class Reference
Detailed Description
This class describes a 2D array of texture tiles.
It is very fast to access a tile given a U and V coordinate in that tile (each tile covers exactly a 1.0 x 1.0 area in UV coordinates, and starts on a whole number) This is used by both the TexturePool class and the CGMaterial class.

}
| void dropAll | ( | ) |
deallocate all textures and clears their states.
Also deallocates the entire TextureTile array and sets the bounds to 0. (which means don't call getLive, getInactiveColor, or getProxyLevel after calling this without first allocating those textures first.
