Subject: [PATCH] mesa: Don't optimize out glClear() if drawbuffer size is 0x0
The driver acquires buffer lazily and may not yet have buffers for
a newly current drawable. In that case the drawable size is 0x0 but
we still need to call into the driver and make it fetch buffers and get
the drawable size.
