The experimental Cogl api cogl_texture_pixmap_new() was recently changed
so it now expects an explicit CoglContext argument and it can also
return exceptions now via a GError. This patch updates mutters use of
the api accordingly.
This was preventing Clutter from running its dispose, preventing
it from being destroyed correctly. While a major bug and possibly
big memory leak, the most obvious effect was the message that Clutter
spat out:
Clutter-CRITICAL **: clutter_actor_iter_next: assertion `ri->age == ri->root->priv->age' failed
Since we never disposed the actor correctly, it was never removed
from its parent, and the age wasn't updated correctly.
Even with --enable-compile-warnings=error, avoid erroring out on deprecations
for the moment, since we are hitting many Clutter deprecations and some are
hard to fix.
When we were shaping the window with a cairo region, there was an easy
optimization to restrict painting only to the pixels we were going to
actually draw. With rounded corners, the amount of work we have to do
figure out what pixels isn't worth the small savings of not drawing the
completely transparent parts of the corners, so remove this optimization,
and the supporting meta_shaped_texture_get_visible_pixels_region()

ClutterTexture has many features that we simply don't use and don't make
sense for a subclass with custom drawing. Deriving directly from ClutterActor
simplifies our code by avoiding workarounds and makes things more robust.
Additionally, make it public. GNOME Shell was already assuming that any
MetaShapedTexture was also a ClutterTexture, and we need to replace these
bits with new API for GNOME Shell to use.

When meta_display_unmanage_window_for_screen() is called, it gets a list
of windows and iterates over them and unmanages them, but unmanaging a
window with attached modal dialogs also unmanages those attached modal
dialogs (in the normal case, temporarily), so we need to guard against
such cases by ref'ing the windows in the list and checking if they have
already been unmanaged.

If we get two configure events on the root window in close
sequence, then we could get the sequence:
ConfigureNotify on the root window w1xh1
Processed by Mutter
clutter_actor_set_size(stage, w1, h1)
<relayout happens, stage window resized by clutter>
ConfigureNotify on the root window, w2xh2
Processed by Mutter
clutter_actor_set_size(stage, w2, h2)
ConfigureNotify on the stage window, w1, h1)
Processed by Clutter
clutter_actor_set_size(stage, w1, h1)
<relayout happens, stage window resized by clutter>
Leaving the stage at the wrong size. To avoid fighting with Clutter,
switch to resizing the stage with XResizeWindow(), similar to how a
toplevel window is handled by a window manager.
For maximized windows, titlebars cannot be used to reposition or
scale the window, so if an application does not use it to convey
useful information (other than the application name), the screen
space occupied by titlebars could be put to better use.
To account for this use case, a setting for requesting that windows'
titlebars should be hidden during maximization has been added to
GTK+, add support for this in the window manager.

Using an external application using libwnck an external application
can create a new workspace by moving a window into it. In this case we
are currently missing a "workspace-added" signal emission.

The current code requires windows to be resizable to be considered
for tiling, which excludes all maximized/tiled windows. While this
restriction concurs with the desired behavior for edge-tiling, it
feels overly restrictive for keybindings.
As the edge-tiling code in update_move() already ensures the above
restriction, it seems save to remove it from the can_tile_maximized()
function, assuming that windows that are not meant to be tiled or
maximized won't provide a maximize function.
