I don't think it is possible to use EXT_client_storage, the image
is not necessarily available when we draw the frame, and we must keep
the buffer available even beyond that.
-dr somewhat avoids this issue, but honestly I haven't seen it make
that much of a difference either, though I realize I haven't tested
on OSX.
