So that users can specify their own area of the shared Texture to use. This allows more flexibility rather than having this functionality restricted to the TextureAtlas class which is specific to one particular approach to texture sharing.
This is a step toward having better support for tile maps such as those produced by the Tiled map editor (http://www.mapeditor.org/)
NOTE: I rejigged my original pull requests to hopefully make them easier to understand and less messy.
If this pull request is not substantial enough on it's own for inclusion then I can probably come back in a couple of weeks with a larger version that adds more functionality. I'm trying to help the best way I can, and am just not sure what the general process is for improving the library as an outsider.
