Bug detailed description:
-------------------------
I'm testing this extension on my G41.
According to the spec of GL_APPLE_object_purgeable, 
"INVALID_OPERATION is generated if either ObjectUnpurgeableAPPLE or
    ObjectUnpurgeableAPPLE is called between the execution of Begin and
    the corresponding execution of End."

Comment 1 Chris Wilson 2010-03-05 02:30:40 UTC 
Checks for Begin/End added:

ASSERT_OUTSIDE_BEGIN_END_WITH_RETVAL(ctx, 0);
