When committing a toplevel surface we might no longer have a MetaWindow
associated with it. The reason may vary but some are: a popup was
dismissed, the client attached and committed a NULL buffer to a
wl_surface with the wl_shell_surface role, the client committed a
buffer to a wl_surface which previously had an toplevel window role
which extension object was destroyed.

If the drag dest surface suddenly disappears, we may find ourselves
processing an XdndPosition message that was sent before the X11 drag
source had an opportunity to find out.
In that case mutter does know, so double check before processing the
messages.
We try to translate the atom with its corresponding mimetype both back
and forth, which actually breaks if the X11 client chose to announce the
mimetype atom. To do the translation properly, keep track on whether the
source announced the UTF8_STRING atom, and reply back with this only if
that happened.
If the wayland surface isn't available yet when we process the
WL_SURFACE_ID ClientMessage, we schedule a later function to try the
association again after we get a chance to process wayland requests.
This works fine except on cases where the MetaWindow already had a
previous surface attached (i.e. when the xwindow is reparented) since
we only break the existing association on the later function which
means that when processing the old surface's destruction we destroy
the MetaWindow and cancel the pending later function leaving us
without a MetaWindow and an invisible surface.
Fix this by detaching the old surface as soon as possible so that the
MetaWindow survives.

The saved rect is used to restore a saved window size. We need to
update this when the window is moved to a monitor with different scale,
so that if we unmaximize a window which was moved to a different
monitor while maximized (for example when unplugged) will restore to
the correct size.

When a window is moved across monitors with different scales, its
rectangle is scaled accordingly. We also need to scale the
unconstrained_rect rectangle, so that moving a window via
meta_window_move_resize() which uses the unconstrained_rect.

ES3 provides glMapBufferRange as core, with the added bonus that it also
supports read mappings. Use this where possible.

GLES2 does not support passing READ to glMapBuffer; attempting to call
cogl_buffer_map for read on ES2 will bring it down with an assert. Make
sure COGL_DEBUG=journal doesn't do this when it's not possible.

Enable animation updates from the GdkFrameClock whenever any timeline is
added to the ClutterMasterClockGdk. This may improve animation
smoothness (depending on the GDK backend in use) because it allows GDK
to tweak its frame timing for animation purposes.

This is how GdkFrameClock is meant to be used: the frame time is meant
to be queried from the GdkFrameClock within its frame signals, rather
from the system monotonic time source.

When removing the frame callback on the CoglOnscreen, we loose the ability
to get notified of swap events. This could leave us with a counter != 0
which leads to a deadlock situation after the next realize/draw cycle.
