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.

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.
The documentation stated:
GTK is a library.… GTK depends on the following libraries:
GTK The GTK library itself contains widgets, that is, GUI
components such as GtkButton or GtkTextView.
There is no point in stating, that the GTK library
depends on the GTK library.
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.

This renders a magnified version of the text,
to make the effect of various font rendering options
more visible.
It also shows the phases of subpixel rendering,
if you have a recent pango and cairo.
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.
