When considering move-region-to-cpu, we need to take into account that
the region may not replace the whole drawable, in which case we cannot
simply dispose of an active CPU bo.

The short-circuit path missed translating the damage from drawable space
into the pixmap (for Composite setups) which may have resulted in
corruption. The path was also failing to consider the impact of reusing
an active CPU bo when it could be discarding the unwanted damage and
reallocating.

Dashed zero-width lines devolve into two passes (first to draw the
foreground dashes, and then to draw the gaps). The code was using the
pixel value to decide which phase was being drawn -- however the color
on the gc is not always bit exact (e.g. alpha channel) with the pixel
value. As a result, we would oft miss drawing anything when rendering
into the scanout.

If we have not had cause to flush the wait_for_shadow buffer during the
course of the rendering, then we never wrote to the backbuffer and its
contents are still identical to the current frontbuffer. So if the
wait_for_shadow is still flagged as required on the scanout, we know we
can safely discard the redisplay request.

set-domain-ioctl should only ever fail for invalid user input, beyond

return from the kernel, check for a GPU hang.

After a successful set-domain for writing with the CPU, we know that the
buffer is idle so remove it from our request tracking. (External clients
complicate matters in that they may keep the bo active even after our
set-domain.) On the contrary, because of read-read optimisations a bo
may still be active after a set-domain for reading by the CPU, in which
we need to remain conservative in retiring the bo.

If the kernel reports an error from setting the DPMS property, we need
to undo the local changes and propagate back the error to the caller.
Although the latter is prevented by the RandR API, we can at least

Composite operations were presumed to cover their entire width x height
area. However, a few paths submit boxes that do not cover the clip
region and so the optimisation made during prepare to discard completely
overwritten data is incorrect (and leads to corruption - stale data is
seen which the client expected to have been overdrawn). So along these
more unusual paths, we must add a flag to prevent the overzealous
discard. Notably, xfce4 triggers this as it uses a lot of unantialiased
trapezoids in its theme drawing.

Commit 50a45a1cdd introduced the use of
"struct stat" but doesn't include <sys/stat.h>. Presumably that leaks
in trough some other header on Linux, but on OpenBSD compilation fails
because the struct isn't known.
