[Mesa3d-dev] APPLE_object_purgeable, ready for inclusion!

[Chris W. <ch...@ch...>]

Thanks to Intel QA providing a few piglit cases to test the API, this has
had a cursory test and identified the silly cases of using the wrong
lookup functions.

The ugly part is that I've used 3 different driver functions to handle
each of the 3 object variants - the alternative would be pass in a void
pointer and a type id. If we acquire more distinct object types, then
multiplexing a single driver function would be preferable to adding
multiple stubs.

Please review and include in 7.7! :)
Thanks,
