      compositor: Add support for opaque regions · e2c690a9
      Olivier Fourdan authored 
      
Opaque region is a hint set by the clients via the _NET_WM_OPAQUE_REGION
property to indicate the compositor which regions of an ARGB window are
considered opaque and therefore can be culled out during repaint.

While this is of little use with regular RGB windows, with the planned
move to client-side decorations in xfce, we'll have more and more ARGB
windows, making such an optimization a beneficial improvement.

      compositor: Make cursor zoom optional · 39eb0435
      Olivier Fourdan authored 
      
Xfwm4 4.14 made the cursor zoom along with the desktop. While this
sounds like a sensible thing to do, it's not necessarily an improvement
for accessibility, because an enlarged cursor also hides what's being
zoomed underneath.

Add a new option to control whether the pointer is zoomed along with the
rest of the desktop.

      More XErrors traps · 3119b50b
      Olivier Fourdan authored 
      
Previously we would leak error traps in free_win_data() causing
slowdowns overtime as the list of requests grows.

While fixing the leak is crucial, it also unveiled several places where
actual error traps are missing, causing xfwm4 to abort more often.

Based on XErrors reported, the issue is triggered when freeing pixmaps
or render pictures.

Add more XErrors traps to catch those errors.

      compositor: Add cwindow_hash to optimize find_cwindow_in_screen · a1fbb8f1
      bob5972 authored and bob5972's avatar bob5972 committed 
      
On my system when the window manager is mostly idling (0-12 tiny
updates per second), about half the CPU time in xfwm4 is spent in
find_cwindow_in_screen, iterating the linked list looking for a
matching Window id.  Instead, this patch adds a GHashTable to map
Window ids to CWindows, completely eliminating that cost in my
profiles, resulting in a 0.3-1.0% of a core total CPU reduction for
this workload.

      compositor: Add define for compositor_timeout_cb interval · 2fa246ca
      bob5972 authored and bob5972's avatar bob5972 committed 
      
The call to g_timeout_add in add_repair seems to be mixing up priority
and callback interval.  Instead, let's call g_timeout_add_full to make
it clear there are two separate fields, and add an appropriate define
for the callback interval, setting it to the same 1ms value it was
currently using.
