* For building atlases at runtime it is very important that:
* - textures be in trucolor/RBGA32 format
* - textures have read flag set
*
*
* It is also Highly recommended to avoid resizing
* - build padding into textures in editor
* - don't use padding when creating atlases
* - don't use tiled materials
*
* If you are having problems look at the Debug Log on the device
