Instead of having renderer API to wait for any number of frames, just
have gsk_gpu_frame_wait() to wait for a single frame.
This unifies behavior on Vulkan and GL, because unlike Vulkan, GL does
not allow waiting for multiple fences.
To make up for it, we replace waiting for multiple frames with finding
the frame with the earliest timestamp and waiting for that one.
Also implement wait() for GL.
This copies the Vulkan idea of using a fence at the end of command
submission and waiting until it gets signaled before reusing the frame.
This frees up the GL driver from doing the work of making buffers etc
reusable and instead allocates new ones when they're still in use and is
a pretty massive performance win.
Print backend can be disposed together with all its printers
as a reaction to user stopping enumeration of printers.
Adding a weak pointer help us to detect that the backend
was disposed and hence the backend and its printers should not
be used anymore.

Most of the time, the image we get for the glyphs will be the
same (the atlas), so avoid adding it to the descriptor set over
and over, and check first if have to. This matches what the
pattern variant of this function already does.
Just initialize the rect directly. This matches better what the
pattern variant of this method does, and it also has the nice
side-effect of eliminating the handling of negative scales in
gsk_rect_scale, which we don't need here, since our scales are
always positive.
Make a single gsk_reload_font helper that can tweak both
scale and font options, so we can ensure that our scaled
font has hint-metrics turned off (pango pays attention to
hint metrics when sizing and rendering hex boxes, and that
hurts us.
Defer the finalization of our GtkTextLineDisplay until we've completed
processing the current frame. Otherwise we risk doing additional work that
could cause us to miss our frame deadline.
Paned handles are hidden when any of its children are hidden too,
but drag events were still accepted around the (virtual) handle position.
Instead, deny drag-begin when handle is hidden.
Fixes#6520Closes#6520
Make this API public so that foreign "text" widgets (e.g. VteTerminal)
have a chance to integrate this logic into their own event controllers,
without having to craft the behavior of their own gestures around the
built-in IM gesture.
In order to make it most useful for other backends, a GdkEvent argument
and a boolean return value were added. This might be useful information
for other platforms than Wayland, e.g. all investigation seems to hint
that on Windows only the a11y keyboard is available programmatically
via app launching, so the IM method implementation would need to set
up its own policies for showing up the OSK (e.g. on touch events).
This makes the conditions in cursor_blinks() more similar to
what GtkText does, and fixes adds the same notify handler for
has-focus, so we start blinking when requires. Crucially, we
also no longer try to blink when unmapped, which should fix
a epiphany crash.
Fixes: #6515
This was showing up as crashes in the testsuite, where a later
test runs the mainloop, and that causes Wayland to claim the
primary selection on a widget that is already disposed.
