Sigh. A serious mixup of integer promotion rules and wraparound caused
the damage computation for small regions to be completely bogus.

When iterating over the active list to mark the current damage, we need
to chase the ->active pointer rather than ->next or else we walk the
wrong list from the wrong starting point.

If we walk the output lists in the same order as they are listed by
RandR, we are more likely to hit favourable priority sorting. E.g. the
user is likely to setup the outputs in the same order as listed, meaning
fewer CRTC transitions etc.

For whatever reason, presumably to do with the switch between CRTCs, we
need to disable the panning before setting the mode in order for our
desired CRTC position to take effect.

X always sends MappingNotify events (there is no way for the client
to ignore them). In particular, MappingNotify would be sent after a VT
switch, and this would knock out our ability to track the cursor..

If all the outputs are off, we try to resize the screen to 1x1, which is
typically illegal. So, just keep the existing screen and xfer buffer for
next time it is enabled.

If the user adds a mode to the VIRTUAL display and then attempts to use
it, add that mode to the remote display.

This reverts commit abf1a16914.
We need to track visibility over all clones on a display, not just the
last.

When we modify the outputs and end up with a different screen size, we
need to actually tell the display to resize with an explicit
XRRSetScreenSize.

XPending() reports if there are any events pending and does not perform
any dequeuing itself - ergo for a remote display while (XPending()) ;
becomes an infinite loop should there be an event pending.

Whilst we want to take over and hide the cursor on the remote displays,
on the source we need to not interfere with the host.

If we fail to track rendering using ShmCompletionEvents and begin to
drop frames, insert an explicit XSync.
