cogl_texture_set_region() and cogl_texture_set_region_from_bitmap() now have a level argument so image data can be uploaded to a specific mipmap level. The prototype for cogl_texture_set_region was also updated to simplify the arguments. The arguments for cogl_texture_set_region_from_bitmap were reordered to be consistent with cogl_texture_set_region with the source related arguments listed first followed by the destination arguments. Reviewed-by: Neil Roberts <neil@linux.intel.com> (cherry picked from commit 3a336a8adcd406b53731a6de0e7d97ba7932c1a8) Note: Public API changes were reverted in cherry-picking this patch
