For drivers that can map system memory into their video memory, the
overhead in utilizing SHM memory directly is in the cost of creating
that mapping. SHM segments are typically much longer lived than either
the Pixmap or Image created within them, and so exposing those for the
driver to map
We pass the pPixmap-drawable.id to the ShmDetachSegment function after
the pPixmap is freed. Fortunately, we don't use the value inside
ShmDetachSegment and can simply pass zero instead.

The flip queue currently only holds events submitted to the driver for
flipping, awaiting the completion notifier. It is short. We therefore
can speed up interrupt processing by keeping the small number of events
ready to be flipped on the end of the flip queue. By appending the
events to the
With large numbers of queued vblank, the list iteration on every
interupt dominates processing time. If we reorder the list to be in
ascending event order, then not only is also likely to be in order for
notification queries (i.e. the notification will be near the start of
the list), we can also

With earlier commit we're including config.h before the system headers.
As such we no longer require the extra define as it is handled/set via
