window: sort icons before adding to _NET_WM_ICON
When processing the list of icons for a window to add them to
_NET_WM_ICON gdk_x11_surface_set_icon_list only adds as many
icon sizes as will fit within X protocol limits.
It achieves this by keeping a running total of the number of
bytes taken up by icons already processed and bails as soon
as it goes over the limit.
The problem is, one 512x512 icon is already over the limit,
and so no icons will get added at all if the first icon in
list is 512x512.
Indeed, the code seems to assume the list is sorted from smallest
icon to biggest icon.
The `name` and `description` events were added to `xdg-output` protocol
in version 2 which is part of wayland-protocols 1.14.
In xdg-output-v1 version 3, the `xdg-output.done` event was deprecated
and the `xdg-output.description` event was made mutable, but that
doesn't change the actual events so we do not actually need to require
that version of xdg-output from wayland-protocols 1.18.
Update the wayland-protocols requirement to the bare minimum version,
which is 1.14.
Pass the glyph position into the glyph caching functions,
not just the glyph index. This allows us to cache different
images for different subpixel positions.

textlayout: introduce caching for GtkTextLineDisplay
This adds a GtkTextLineDisplayCache which can be used to cache a number
of GtkTextLineDisplay (and thus, PangoLayout) while displaying a view.
It uses a GSequence to track the position of the GtkTextLineDisplay
relative to each other, a MRU to cull the least recently used display,
and and a direct hashtable to lookup display by GtkTextLine.
We only cache lines that are to be displayed (!size_only). We may want to
either create a second collection of "size_only" lines to speed that up,
or determine that it is unnecessary (which is likely the case).
We are currently using a weird mix of pango and cairo,
but there is no need for us to go through a pango
renderer here; we can just use cairo directly.
These are too sensitive to rendering differences
between renderers to run reliably in ci, but we
still want to keep them around. In particular,
the big glyph tests are useful to exercise the
GL glyph cache.
xdg-output v3 marks xdg-output.done as deprecated and compositors are
not required to send that event anymore.
So if the xdg-output version is 3 or higher, simply set the initial
value `xdg_output_done` to TRUE so we don't wait/expect that event
from the compositor.

gdk: Remove gdk_surface_move_resize() API
Windows/surface's aren't supposed to be explicitly moved by any external
part, so don't provide API for doing so. Usage throughout Gdk is
replaced by the corresponding backend variants.

gdk: Make backends implement move_to_rect()
The generic layer still does the heavy lifting, leaving the backends
more or less just act as thin wrappers, dealing a bit with global
coordinate transformations. The end goal is to remove explicit surface
moving from the generic gdk layer.

gdk/surface: Add toplevel_resize vfunc
To separate how toplevels and popups are configured, a first step is to
introduce a resize-only vfunc for backends to implement. It's meant to
only configure toplevel windows, i.e. popups. Currently it's used for
both types, but introducing the resize-only API is a first step.
Don't insert text attributes if the font, or scale
or fallback did not actually change. This helps
Pango avoid excessive item breaks, which in turn
helps shaping to work across things like color
changes.

wayland: Cleanup surface configuration
Configuration should happen in response to the xdg_surface.configure
event, not in the events that preceeds it. Do this by making all
configured state pending until the committing "configure" event. Also
split up toplevel vs popup configuration in a more clear way.
textlayout: make GtkTextLineDisplay reference counted
This makes GtkTextLineDisplay use GRcBox instead of g_slice_*
directly. By using reference counting for this structure, we
can ensure that we hold an extra ref for one_display_cache as
well as caching additional GtkTextLineDisplay for the visible
range in the future.
Update the cached text style when a css change affects
content or background. This fixes text views drawing
black-on-dark when switching to the dark theme.
This removes the use of GtkTextDisplay (a PangoRenderer) to use
the GskPangoRender which generates render nodes. Part of this means
improving the GskPangoRenderer to support the necessary features for
displaying a GtkTextView.
Primarily, this is a merging of GtkTextDisplay features into
GskPangoRender. Additionally, GtkTextDisplay was removed to allow for
gtk_text_layout_snapshot() to be implemented elsewhere.
