Allow specifying padding via --padding. The argument to --padding
is a string of up to 4 comma-separated numbers, for the left, right,
top, bottom padding. If less numbers are given, the remaining ones
are set to zero.
This commit also includes an image that can be used for testing with
testdmabuf --padding 20,20,20,20 NV12 padded.png
Make the picture not expand, and add Ctrl-S to toggle the
horizontal alignment between start and center. This makes the
offloaded picture move under the overlaid controls, or out
from under them, triggering some offloading transitions.
If we can't open /dev/dma_heap/system, fall back to using memfd_create.
It does not let us make a 'proper' dmabuf, but it is good enough to
test our handling of linear buffers in various formats.
The code now by default puts all planes into the same fd - like
v4l does, too.
The old behavior of one fd per plane can be enabled via --disjoint.
Also, am --undecorated option has been added so that the window
isn't decorated and all that the renderer has to do is display the
dmabuf.
This is useful when debugging just the dmabuf rendering.
This uses the dma-heap kernel api to create a dma-buf
and use it for a GdkDmabufTexture. It supports a few
formats to test how well GL conversion of YUV works.
The YUV code is adapted from weston tests.
This is implemented using a new xdg_toplevel `suspended` state, and is
meant for allowing applications to know when they can stop doing
unnecessary work and thus save power.
In the other backends, the `suspended` state is set at the same time as
`minimized` as it's the closest there is to traditional windowing
systems.
We were clowing through all the Pango caches for no benefit.
It made the test generation stuck in fontconfig loops instead of
quickly generating tests.
So don't do that and limit the different fonts to some reasonable list
of options.
It turns out that the old behavior of GTK_ALIGN_BASELINE
was actually used in libadwaita, so bring it back, and
introduce a new GtkAlign value for the new behavior.
That way, local scrolling is available and the scrolling isn't random.
Recycling should now involve reordering the recycled widgets instead of
just keeping their order because all of them got recycled.
The GL Wayland drag surface code path has a bug where it does not reset
the hotspot, so if a GL-backed draw surface redraws without resizing or
resetting the hotspot, it moves away. The next commit will fix that, but
this commit adds a test for that.
The design patterns using statusbar are no longer popular,
and it is pretty easy to make a statusbar yourself with boxes
and labels, if you need one. The only thing special about
GtkStatusbar was its window resize handle, but that has
been gone for a long time.
