Clutter does the nicety of connecting just created PangoContexts to
ClutterBackend signals in order to update it on resolution/font changes.
However the way the signals are disconnected (automatically via
g_signal_connect_object() auto-disconnect feature) may incur into
performance issues with a high enough number of ClutterActors with a
PangoContext (eg. ClutterText) as the lookup by closure is linear across
all signals and handlers.
Keep the handler IDs around, and disconnect them specifically on dispose
so it is more O(1)-ish.

The clutter/evdev implementation of mousekeys is designed after the
current implementation in X11, and works when the setting is enabled
regardless of the status of NumLock.
The GNOME documentation on accessibility features states however that
mousekeys work only when NumLock is OFF:
https://help.gnome.org/users/gnome-help/stable/mouse-mousekeys.html
Change the clutter/evdev implementation to match the documentation, i.e.
disable mousekeys when NumLock in ON so that switching NumLock ON
restores the numeric keypad behaviour.

The keyboard accessibility setting "enable" is actually even more
misleading that initially anticipated, as it does not control the
entire keyboard accessibility feature, but just the "enable by
keyboard" feature, i.e. being able to enable or disable stickykeys
or slowkeys using various keyboard actions.
Yet the accessibility features should still work even if the "enable"
setting is unset, those can be controlled by the accessibility menu in
GNOME Shell for example.
Change the clutter/evdev implementation to match that behavior as found
in the x11 backend, so both backends are now consistent.

In a multi-monitor setup there is a separate paint run for each monitor.
If an actor doesn't intersect the first monitor painted then it is culled
out for that monitor to save time. Unfortunately this would mean
`clutter_actor_paint` was setting `is_dirty = FALSE` before the actor had
yet been painted on any monitor.
This meant that effects like `ClutterOffscreenEffect` were not receiving
the flag `CLUTTER_EFFECT_PAINT_ACTOR_DIRTY` when they should have, and
so would rightfully think they don't need to do a full internal
invalidation. So `ClutterOffscreenEffect`, and probably other effects,
did not repaint correctly unless on the first monitor in the list.
The fix is to simply avoid setting `is_dirty = FALSE` on those paint
runs where the actor has been culled out (`clutter_actor_continue_paint`
wasn't called). It is only safe to clear the flag after
`clutter_actor_continue_paint` has been called at least once per stage
paint.

clutter_input_device_get_physical_size was just used for device mapping
heuristics in MetaInputMapper. It now started using the info from udev
on for both backends, so this means this clutter API is no longer
necessary.

Enabling keyboard accessibility features on Wayland from the keyboard
was wrongly assumed to be controlled by the "togglekeys" setting,
whereas it should be simply controlled by the "enable" setting.
As "togglekeys" is off by default and doesn't have a UI option to
enable, that would prevent turning on or off the keyboard accessibility
features using the keyboard.

Meson 0.50.0 made passing an absolute path to install_headers()'
subdir keyword a fatal error. This means we have to track both
relative (to includedir) paths for header subdirs and absolute
paths for generated headers now :-(

The ClutterVirtualInputDevice API was fixed to use Clutter button
internal codes, whereas the mousekeys still uses evdev codes.
Change the mousekeys implementation to use the Clutter button code
instead to remain compatible with the ClutterVirtualInputDevice API.

Since e3e933c4 a keyval can be temporarily remapped to an unused keycode. Due to
some limitations in XTestFakeKeyEvent, the remapping has to be done in the first
xkb group/layout. In case there are two or more keyboard layouts enabled and the
selected keyboard layout is not the first, clutter_keymap_x11_keycode_for_keyval
will fail to retrieve the correct keycode for a remapped keyval. Let's use the
reserved_keycodes map in order to retrieve the correct keycode if needed.

The clamped rectangle currently could not fully contain the original fractional
rectangle because it doesn't take care of the fact that the new width should
consider the fact that flooring we'd translate the rectangle, and thus to cover
the same area we need to take care of it.
So, to properly compute the width and height, calculate x2 and y2 first and then
use this ceiled value to compute the actual width using the floored x1 and y1.

When we try to update the FB, we might face the case in which the effect target
framebuffer does not need any redraw, because it's already properly sized and
scaled, but the filter applied to the pipeline is not, because it has been
computed for a non-fractional scaling.
This is happens for example to clutter actors with a flattening effect (i.e.
override redirect mode set), that might have been generated properly for a
celied scaling level, but when we go fractional we need to ensure to use a
linear filter, as the 1:1 texel:pixel assumption is not true anymore.

At this level we use ceiled resource-scale when painting fractional value
When using fractional scaling we still need to create an integer-sized
texture and then we should paint it using a size which is proportional
to the real actor size ratio, and only paint a subsample of it, but this
doesn't seem to work properly with some weird scaling values.
Then, it's just better to draw the texture ceiled and then we scale it
down to match the proper actor scaling at paint level.

When resource scale is set we need to generate a scaled PangoLayout (by adding
a new scale attribute, or adjusting the one we already have according the
resource scale), then it has to be painted with proper scaling matrix.
So everything that has to do with PangoLayout has to be in real coordinates,
then clutter logical coords multiplied by resource scaling.
While the actual size of the layout is the one of the PangoLayout divided by
resource scale.
We map the text positions to logical coords by default, while using
the pixel coordinates when painting.
We fall back to scale 1 when calculating preferred size if no scale is
known. The pango layout will not have set a layout scale attribute,
meaning it'll be 1, thus we should just assume the layout scale is 1 here.
Not doing so might result in the preferred size being 0x0 meaning the
actor won't be laid out properly.

A clutter actor might be painted on a stage view with a view scale
other than 1. In this case, to show the content in full resolution, the
actor must use a higher resolution resource (e.g. texture), which will
be down scaled to the stage coordinate space, then scaled up again to
the stage view framebuffer scale.
Use a 'resource-scale' property to save information and notify when it
changes.
The resource scale is the ceiled value of the highest stage view scale a
actor is visible on. The value is ceiled because using a higher
resolution resource consistently results in better output quality. One
reason for this is that rendering is often not perfectly pixel aligned,
meaning even if we load a resource with a suitable size, due to us still
scaling ever so slightly, the quality is affected. Using a higher
resolution resource avoids this problem.
For situations inside clutter where the actual maximum view scale is
needed, a function _clutter_actor_get_real_resource_scale() is provided,
which returns the non-ceiled value.
Make sure we ignore resource scale computation requests during size
requests or allocation while ensure we've proper resource-scale on
pre-paint.
