Instead of directly using a guint32 to store a bitmask for each used texcoord array, it now stores them in a CoglBitmask. This removes the limitation of 32 layers (although there are still other places in Cogl that imply this restriction). To disable texcoord arrays code should call _cogl_disable_other_texcoord_arrays which takes a bitmask of texcoord arrays that should not be disabled. There are two extra bitmasks stored in the CoglContext which are used temporarily for this function to avoid allocating a new bitmask each time. http://bugzilla.openedhand.com/show_bug.cgi?id=2132
