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.
