This flag must be set when creating the class or offloading
will be disabled for this renderer.
Set that flag for the GL renderer.
Fixes the Cairo and Vulkan renderer not showing Video.
Map GTK_ACCESSIBLE_RELATION_COL_INDEX_TEXT and
GTK_ACCESSIBLE_RELATION_ROW_INDEX_TEXT to the
corresponding AT-SPI object attributes
"colindextext" and "rowindextext", as it is specified
e.g. in the Core Accessibility Mappings 1.2 for the
corresponding attributes [1] [2].
Orca makes use of these object attributes in web browsers
and since recently also for LibreOffice [3] and is
planning to use that more globally.

These tests come in two variants.
The first takes .node and .offload file, parses the node file,
and compares the resulting subsurface attachments to expected results.
The second variant takes two .node/.offload file pairs and a .diff
file, parses the node files, compares the resulting subsurface
attachments, and then diffs the nodes, comparing the resulting
area to the region in the .diff file.
This is new widget that will attempt to pass through the content
of its child via a subsurface. This is mostly meant for internal
use, but the minimal api is available.
During rendering, restack offloaded subsurfaces below the main
surface, and clear the area so they peek through. After rendering,
raise the last subsurface if we haven't drawn over it.
Add a blend mode to the draw command, so it can draw transparent
black. This will be used to erase the area on top of a subsurface
when we do passthrough.
Add an extra argument to pass offload info to the diffing code.
This is then used for diffing subsurface nodes differently,
depending on their offloading status.
We have to be careful to not draw over the subsurface area with
our highlighting, otherwise this would interfere with raising
unobstructed subsurfaces.
Add api to allow creating subsurfaces, attaching textures to them,
and changing the stacking order.
This is just the api, there is no implementation yet.
This is a backport of !1143 to gtk4.
SetClipboardViewer() API is obsolete is prone to clipboard chain breaks
from other applications.
Use recommended AddClipboardFormatListener() instead.
Fixes#442
`gtk_window_get_default_size()` claims width/height are optional-out
arguments, but defers to `gtk_window_get_remembered_size()` which
may dereference a NULL-pointer.
Since `gtk_window_get_remembered_size()` is only called by
`gtk_window_get_default_size()`, collapse it into the latter
and perform the NULL check there.
Make sure all our dmabuf debug messages are display-scoped so the
inspector doesn't trigger them, use the same formatting throughout,
and improve consistency of wording here and there.
