This exposes the CoglAtlasTexture api, making the following public: cogl_atlas_texture_new_with_size cogl_atlas_texture_new_from_file cogl_atlas_texture_new_from_data cogl_atlas_texture_new_from_bitmap The plan is to remove auto-texture apis like cogl_texture_new_from_file since they are a bit too magic, but that means we need an explicit way for users to allocate texture that will go in the atlas. Although the _new_from_file() api is arguably redundant since you can use _bitmap_new_from_file() followed by _atlas_texture_new_from_bitmap() we don't want to loose any of the convenience that cogl_texture_new_from_file() had.
