Unlike in GObject the type number for a CoglObject is entirely an internal implementation detail so there is no need to make a GQuark to make it safe to export out of the library. Instead we can just directly use a fixed pointer address as the identifier for the type. This patch makes it use the address of the class struct of the identifier. This should make it faster to do type checks because it does not need to call a function every time it wants to get the type number. Reviewed-by: Robert Bragg <robert@linux.intel.com>
