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.
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.
`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.
Getting this wrong matters, since we won't offload textures in
non-opaque formats. Found by Robert Mader. At the same time,
unify the two places we have for mapping from fourcc to memory
format.
Deep trees quickly add so much empty space on the left, so that it gets
really hard to read after an indentation level of ~10.
By halving, we still keep the visual clarity of indenting but we can now
handle twice as many indentation levels, ie ~20.
It is what sysprof has been using, and it also feels right in the
inspector.
