_SVID_SOURCE has been deprecated in newer versions of glibc breaking
-WError; the recommended replacement of _DEFAULT_SOURCE is fairly
new, so switch to _XOPEN_SOURCE instead.
The "original coordinates" passed into meta_window_place() were the
coordinates of the client rectangle not the frame rectangle. When
meta_window_place() didn't place because the window was manually
positioned (e.g., 'xterm -geometry +x+y') that resulted in a window
being offset by the frame dimensions.

Since the introduction of frame sync in GTK+, updates to titlebar font and
colors haven't been working because GTK+ counts on the frame clock to
do style updates, and the frame clock doesn't run for an unmapped
GdkWindow. (It's possible that GtkStyleContext changes subsequent to
the introduction of the frame clock were also needed to fully break
things.)
We actually need to map the MetaFrames GdkWindow and let the
compositor code send out the frame sync messages in order to pick up
style changes.
Hopefully no bad side effects will occur from this - we make the window
override-redirect, 1x1, and outside the bounds of the screen.

We need to resolve the keycode from the keysym again since the keycode
might have changed if there was a keymap switch between the grab and
the ungrab.
Before starting to use display_get_keybinding() we could compare
MetaKeyBinding.modifiers with MetaKeyCombo.modifiers directly. Now, we
need to resolve the virtual modifiers to match with the mask.
This allows us to look for a match with an O(1) search instead of O(n)
which is nice, particularly when running as a wayland compositor in
which case we have to do this search for every key press event (as
opposed to only when our passive grab triggers in the X compositor
case).
We actually need two hash tables. On one we keep all the keybindings
themselves which allows us to add external grabs without constantly
re-allocating the array we were using previously.
The other hash table is an index of the keybindings in the first table
by their keycodes and mask which is how we actually match the key
press events. This second table thus needs to be rebuilt when the
keymap changes since keycodes have to be resolved then but since we're
only keeping pointers to the first table it's a fast operation.

Instead of looping over an array of keybindings to find the correct
binding, just use display_get_keybinding().
In the next commit, we'll change the array to be a hash map, so this
helps the patch be cleaner.

Creating a new cogl texture may fail, in which case the intent to
free it will crash. While something is clearly wrong (insanely
large window, oom, ...), crashing the WM is harsh and we should
try to avoid it if at all possible, so carry on.

We don't want to match the keysym so that e.g. an accelerator
specified as "<Super>a" works if the current keymap has a keysym other
than 'a' for that keycode which means that the accelerator would
become inaccessible in a non-latin keymap.
This is inconvenient for users that often switch keyboard layouts, or
even have different layouts in different windows, since they expect
system-level keybindings to not be affected by the current layout.

For decorated windows, we don't want to apply any input
shape, because the frame is always rectangular and eats
all the input.
The real check is in meta-window-actor, where we consider
if we need to apply the bounding shape and the input shape
(or the intersection of the two) to the surface-actor,
but as an optimization we avoid querying the server in
meta-window.
Additionally, for undecorated windows, the "has input shape"
check is wrong if the window has a bounding shape but not an
input shape.
... and individually. It turns out that updating the opaque region
was causing the shape region to be updated, which was causing a new
shape mask to be generated and uploaded to the GPU. Considering
GTK+ regenerates the opaque region on pretty much any focus change,
this is not good.
The handler pointer is dangling in MetaKeyBinding until
rebuild_key_binding_table() is run, so we can't dereference it.
Because we only need the flags at ungrab time, store a copy
in the MetaKeyBinding structure.

If the last reference of a MetaIdleMonitor is held by the caller, it may
happen that the last reference is lost when calling the GDestroyNotify,
if this happens when the watched DBus name vanishes, the object (and the
watches hashtable) are destroyed while manipulating the watches hashtable,
so bad things may happen then.
Fix this by wrapping the operation by a ref/unref pair, so the object would
be destroyed after operating on the hashtable.

We cannot intersect the the complete volume with the unobscured bounds
because it does not include the shadows. So just intersect it with the
windows's shape bounds and union it with the shadow bounds.
This also matches what the comment in the code says:
"We could compute an full clip region as we do for the window texture,
but the shadow is relatively cheap to draw, and a little more complex to clip,
so we just catch the case where the shadow is completely obscured
and doesn't need to be drawn at all."
Switching meta/util.h to gi18n.h was wrong, mutter is a library
and needs gi18n-lib.h, but that cannot be included from a public
header (since it depends on config.h or command line options),
so split util.h into a public and a private part.

In order for the compositor to properly determine whether a client
is an X11 client or not, we need to wait until XWayland calls
set_window_id to mark the surface as an XWayland client. To prevent
the compositor from getting tripped up over this, make sure that
the window has been fully initialized by the time we call
meta_compositor_add_window.

Traditionally, WMs unmap windows when minimizing them, and map them
when restoring them or wanting to show them for other reasons, like
upon creation.
However, as metacity morphed into mutter, we optionally chose to keep
windows mapped for the lifetime of the window under the user option
"live-window-previews", which makes the code keep windows mapped so it
can show window preview for minimized windows in other places, like
Alt-Tab and Expose.
I removed this preference two years ago mechanically, by removing all
the if statements, but never went through and cleaned up the code so
that windows are simply mapped for the lifetime of the window -- the
"architecture" of the old code that maps and unmaps on show/hide was
still there.
Remove this now.
The one case we still need to be careful of is shaded windows, in which
we do still unmap the client window. In the future, we might want to
show previews of shaded windows in the overview and Alt-Tab. In that
we'd also keep shaded windows mapped, and could remove all unmap logic,
but we'd need a more complex method of showing the shaded titlebar, such
as using a different actor.
At the same time, simplify the compositor interface by removing
meta_compositor_window_[un]mapped API, and instead adding/removing the
window on-demand.

If we fail to find the IDLETIME counter, then the alarm variable will be
uninitialised. Most code paths are careful to check this before
submitting XSync calls, but there is one check missing.
