The event may end up freed after delivery, ensure to keep a ref in order
to emit the matching emulated crossed event matching a proximity event.

We can avoid recreating a number of text nodes from render_para() on
sub-sequent runs if we cache the rendernode instead of just the
PangoLayout.
When used with GtkSourceMap, this can yield a ~7 FPS improvement during
smooth scrolling at the cost of some more memory.
The code managing this accounting mixed seat and tablet output lists,
can't bode well. Fixes invalid reads on list elements, as there are
dangling pointers.

This is the Vulkan version of eglSwapBuffersWithDamage(), and
it's always a good idea to limit the number of pixels we're
pushing to the GPU and/or swapping into the display.
UNDEFINED initial layouts may not preserve the contents
of the attachment after transitioning the layout. We want
them to be preserved because we do partial rendering.
Use GENERAL as the initial layout for render passes.
Multiple images in the before barrier array are defined with
VK_ACCESS_TRANSFER_WRITE_BIT and VK_ACCESS_TRANSFER_READ_BIT,
which requires passing VK_PIPELINE_STAGE_TRANSFER_BIT and
VK_PIPELINE_STAGE_HOST_BIT to vkCmdPipelineBarrier().
Pass these flags correctly.
This is a requirement for using VK_KHR_incremental_present.
Vulkan Wayland drivers translate the VkPresentRegionsKHR to
wl_surface.damage_buffer(), which a v4-only request.
This creates a new GtkTextViewChild that can manage overlay children at
given x,y offsets in buffer coordinates. This simplifies GtkTextView by
extracting this from GtkTextWindow as well as providing a real widget for
the borders.
With this change, we also rename gtk_text_view_add_child_in_window() to
gtk_text_view_add_overlay(). For those that were using
GTK_TEXT_WINDOW_WIDGET, they can use a GtkOverlay. It does not appear
that anyone was using GTK_TEXT_WINDOW_(LEFT|RIGHT|TOP|BOTTOM) for widgets
in this fashion, but that can be done by setting a gutter widget with
gtk_text_view_set_gutter(). We can make GtkTextViewChild public if
necessary to simplify this should it become necessary.
GtkTextViewChild will setup a CSS node of either "text" or "border"
depending on the GtkTextWindowType.
The old GtkTextViewChild has been renamed to AnchoredChild as it is only
used for widgets with anchors in the GtkTextBuffer. This also removes the
use of allocated GSList and instead embeds a GQueue and GList to save a
few extraneous allocations.
