The "backends: Move MetaOutput::crtc field into private struct"
accidentally changed the view transform calculation code to assume that
"MetaCrtc::transform" corresponds to the transform of the CRTC; so is
not the case yet; one must calculate the transform from the logical
monitor, and check whether it is supported by the CRTC using
meta_monitor_manager_is_transform_handled(). This commit restores the
old behaviour that doesn't use MetaCrtc::transform when calculating the
view transform.

A just focused ClutterInputFocus must set itself up correctly on
all situations. Refactor this into a function, so it can be used
for the case where a ClutterText gets editable while focused.
XcursorLibraryLoadCursor can return 'None' if the current cursor theme
is missing the requested icon. If XFreeCursor is then called on this
cursor, it generates a BadCursor error causing gnome-shell to crash.

We need a way for mutter to exit if no available GPUs are going to work.
For example if gdm starts gnome-shell and we're using a DRM driver that
doesn't work with KMS then we should exit so that GDM can try with Xorg,
rather than operating in headless mode.

As per specification

This fixes culling problems under certain conditions.
`ClutterText` painting for editable single_line_mode actors like `StEntry`
is always clipped by:
`cogl_framebuffer_push_rectangle_clip (fb, 0, 0, alloc_width, alloc_height)`
So it's difficult to get the rectangle wrong. However in cases where the
target framebuffer has changed (`cogl_push_framebuffer`) such as when
updating `ClutterOffscreenEffect` we had the wrong old value of `fb`. And
so would be clipping the wrong framebuffer, effectively not clipping at all.
Currently xdg-shell applies a geometry set with set_window_geometry
unconditionally. But the specification requires:
> When applied, the effective window geometry will be
> the set window geometry clamped to the bounding rectangle of the
> combined geometry of the surface of the xdg_surface and the
> associated subsurfaces.
This is especially important to implement viewporter and
transformation.
By using the shm file when sending the keymap to all clients, we
effectively allows any client to change the keymap, as any client has
the ability to change the content of the file. Sending a read-only file
descriptor, or making the file itself read-only before unlinking, can
be worked around by the client by using chmod(2) and open(2) on
/proc/<pid>/<fd>.
Using memfd could potentially solve this issue, but as the usage of
mmap with MAP_SHARED is wide spread among clients, such a change can
not be introduced without causing wide spread compatibility issues.
So, to avoid allowing clients to interfere with each other, create a
separate shm file for each wl_keyboard resource when sending the
keymap. We could eventually do this per client, but in most cases,
there will only be one wl_keyboard resource per client anyway.

If a client maps a popup in response to a key-down event, but the
mapping doesn't occur until after the user has already released the same
button, we'd immediately dismiss the popup. This is problematic, as one
often presses and releases a key quite quickly, meaning any popup mapped
on key-down are likely to be dismissed.
Avoid this race condition by accepting serials for key down events, if
the most recent key-up event had the same keycode.

This protocol supersedes the internal gtk_text_input protocol that
was in place. Functionally it is very similar, with just some more
verbosity in both ways (text_change_cause, .done event), and some
improvements wrt the pre-edit text styling.
meta_backend_x11_grab_device is performing X server clock comparison
using the MAX macro, which comes down to a simple greater-than.
Use XSERVER_TIME_IS_BEFORE, which is a better macro for X server
clock comparisons, as it accounts for 32-bit wrap-around.

Sending button events to a ClutterVirtualInputDevice, the API expects
button codes to be of the internal clutter type. The evdev
implementation incorrectly assumed it was already prepared evdev event
codes, which was not the case. Fix the evdev implementation to translate
from the internal representation to evdev before passing it along to
ClutterSeatEvdev.

Commit c0d9b08ef9 replaced the old GBM API calls
with the multi-plane GBM API. However, the call to gbm_bo_get_handle_for_plane
fails for some DRI drivers (in particular i915). Due to missing error checks,
the subsequent call to drmModeAddFB[2] fails and the screen output locks up.
This commit adds the missing error checks and falls back to the old GBM API
(non-planar) if necessary.
v5: test success of gbm_bo_get_handle_for_plane instead of errno
This commit adopts solution proposed by Daniel van Vugt to check the return
value of gbm_bo_get_handle_for_plane on plane 0 and fall back to old
non-planar method if the call fails. This removes the errno check (for
ENOSYS) that could abort if mesa ever sets a different value.

If the surface is gone before `meta_xwayland_keyboard_grab_end()` is
called, we would bail out early leaving an empty grab, which will cause
a segfault as soon as a key is pressed later on.
Make sure we clean up the keyboard grab even if the surface is gone.

Children added to a parent after that parent (or its ancestors)
have already been cloned now inherit the clone branch depth of
the parent. Otherwise `clutter_actor_is_in_clone_paint` on the child
could return FALSE when it should have been returning TRUE.
The string used to point to memory owned by libwayland-server, but
with the ability to override the display name, we took over ownership
by copying the string as necessary.

The function is intentionally provided as macro to not require a
cast. Recently the macro was improved to check that the passed in
pointer matches the free function, so the cast to GDestroyNotify
is now even harmful.

Thanks to G_DEFINE_DYNAMIC_TYPE_EXTENDED(), this is a trivial addition that
will allow using G_IMPLEMENT_INTERFACE_DYNAMIC() or G_ADD_PRIVATE_DYNAMIC()
when declaring a plugin.
