6b5cf2eb61 compositor: Add a new window group for override-redirect windows
Put override redirect windows such as menus into a separate window group
stacked above everything else. This will allow us to visually put these
above other compositior chrome.

Based on a patch from Muffin.

87fe9685b5 Distinguish "no delay" frames from spontaneous drawing
When a client is drawing as hard as possible (without sleeping
between frames) we need to draw as soon possible, since sleeping
will decrease the effective frame rate shown to the user, and
can also result in the system never kicking out of power-saving
mode because it doesn't look fully utilized.

Use the amount the client increments the counter value by when
ending the frame to distinguish these cases:

 - Increment by 1: a no-delay frame
 - Increment by more than 1: a non-urgent frame, handle normally

2d9b8bb2d0 Send _NET_WM_FRAME_TIMINGS messages
We previously had timestamp information stubbed out in
_NET_WM_FRAME_DRAWN. Instead of this, add a high-resolution timestamp
in _NET_WM_FRAME_DRAWN then send a _NET_WM_FRAME_TIMINGS message
after when we have complete frame timing information, representing
the "presentation time" of the frame as an offset from the timestamp
in _NET_WM_FRAME_DRAWN.

To provide maximum space in the messages,_NET_WM_FRAME_DRAWN and
_NET_WM_FRAME_TIMINGS are not done as WM_PROTOCOLS messages but
have their own message types.

74b1a9e2b9 Add meta_compositor_monotonic_time_to_server_time()
Add a function to convert from g_get_monotonic_time() to a
"high-resolution server timestamp" with microsecond precision.
These timestamps will be used when communicating frame timing
information to the client.

d8696c17be Use clutter_stage_set_sync_delay()
Using a "sync delay" where we wait for 2 ms after the vblank before
starting to draw the next frame provides for much more predictable
latency for applications. An application can know that if it completes
a frame any time between 8ms before the vblank to the vblank,
it will reliably be drawn on the following vblank period, rather than
having an unpredictable latency depending on whether the compositor
is currently busy drawing a frame or not.

b07aea467e Enable CLUTTER / COGL_ENABLE_EXPERIMENTAL_API globally
Instead of defining CLUTTER_ENABLE_EXPERIMENTAL_API and
COGL_ENABLE_EXPERIMENTAL_API in individual source files, enable
them on the command line. We weren't tracking exactly what pieces of
experimental API we were using and we were using the experimental
API in most source files that used Clutter and Cogl, so the
local #defines were annoying rather than useful.

04ef448927 Handle _NET_WM_SYNC_REQUEST_COUNTER updates without redraw
It's possible that a client might update the (extended)
_NET_WM_SYNC_REQUEST_COUNTER counter twice without actually drawing
anything. In that case, we still should send a _NET_WM_FRAME_DRAWN
message since it's hard for a client to know every case in which
no damage is generated. For now, do it the easy way by forcing a
stage repaint.

c9343e3ee3 Implement freezing of updates during resize
Replace the unused meta_compositor_set_updates() with
a reversed-meaning meta_compositor_set_updates_frozen(), and use
it to implement freezing application window updates during
interactive resizing. This avoids drawing new areas of the window
with blank content before the application has a chance to repaint.

a613a55658 Support _NET_WM_OPAQUE_REGION
This new hint allows compositors to know what portions of a window
will be obscured, as a region above them is opaque. For an RGB window,
possible to glean this information from the bounding shape region of
a client window, but not for an ARGB32 window. This new hint allows
clients that use ARGB32 windows to say which part of the window is
opaque, allowing this sort of optimization.

90f2a3ae4c mutter-window-actor: Improve unredirect heuristic
Currently we only unredirect monitor sized override redirect windows.
This was supposed to catch fullscreen opengl games and improve
their performance.

Newer games like fullscreen webgl games and SDL2 using games (like L4D) as well as wine based games do not use override redirect windows so we need a better
heuristic to catch them.

GLX windows always damage the whole window when calling glxSwapBuffers and
never damage sub regions. So we can use that to detect them.

The new heuristic unredirects windows fullscreen windows that have damaged the
whole window more then 100 times in a row.

424fc5245a Add compositor hook to process keybindings selectively
Currently keybindings are blocked while the compositor holds a grab; if
we want a keybinding to be available anyway, we use captured ClutterEvents
to determine the KeyBindingAction the event would have triggered and
run our own handlers (ugh).
Instead, provide a hook to allow the compositor to filter out keybindings
before processing them normally, regardless of whether the compositor
holds a grab or not.

bc96a14185 window-group: Subtract the unredirected window in stage space
meta_window_group_paint tries to carefully figure out which parts of the
scene it can avoid painting. One area it avoids painting is the region of
the screen occupied by an unredirected window (if there's one present).
When subtracting from the visible region, it gets the coordinate spaces
confused, and ends up subtracting the area at the wrong offset. Fix this
by translating the rectangle subtracted from the visible region.
