Running with WLR_BACKENDS=headless, there is no keyboard device.
Avoid crashes like so:
../tinywl/tinywl.c:136:2: runtime error: member access within null pointer of type 'struct wlr_keyboard'
../tinywl/tinywl.c:136:2: runtime error: member access within null pointer of type 'struct wlr_keyboard'

Instead of waking up each 16ms to emit a frame event, arm the timer
when the output is committed. This allows the headless backend to
idle when nothing changes on screen, and behaves similarly to the
other backends.
The current ARGB2101010 has really "corase" control over the alpha.
Particularily, examples/layer-shell would look really strange with certain
parameters. For examples, when passing an alpha of 0.84, the box would not
appear transparent at all anymore.
Patched as suggested by @mstoeckl -- thank you!
These formats require EXT_texture_norm16, which in turn needs OpenGL
ES 3.1. The EXT_texture_norm16 extension does not support passing
gl_internalformat = GL_RGBA to glTexImage2D, as can be done for
formats available in OpenGL ES 2.0, so this commit adds a field to
wlr_gles2_pixel_format to provide a more specific internalformat
parameter to glTexImage2D.
The spec reads:
> All paths set in these environment variables must be absolute. If an
> implementation encounters a relative path in any of these variables it should
> consider the path invalid and ignore it.
and
> If $XDG_DATA_HOME is either not set or empty, a default equal to
> $HOME/.local/share should be used.
Testing that the path is absolute also entails that is is non-empty.
Add a src_box state field. Use the SRC_* KMS props in the DRM
backend, reject the layers in the Wayland backend (for now, we can
support it later via viewporter).
This makes seat_client resources inert when seats and/or input devices are
destroyed, rather than destroying the resources.
When the client calls e.g. wl_keyboard_release(), it's not expecting the
keyboard global to be already destroyed, so this results in an error such
as this:
wl_display@1: error 0: invalid object 22
Setting the GLESv2 parameter GL_PACK_ALIGNMENT to 1 ensures that the
stride of the glReadPixels output matches the value computed in
`pack_stride`. Since the default value of GL_PACK_ALIGNMENT is 4, this
does not make a difference under normal use; but without this patch
the stride can be incorrect; for example, with RGB565 buffers and
screenshots of regions with odd width.
wlr_output is not well-suited to checking whether direct scan-out
is happening or not. Compositors may want to use their own external
swapchains, for instance.
Additionally, ab7eabac84 ("output: leverage
wlr_output_configure_primary_swapchain()") makes it so
output_basic_test() is called before the output swapchain is
initialized, resulting in false positives.

This allows callers to set a destination size different from the
buffer size to scale them.
The DRM backend supports this. The Wayland backend doesn't yet
(we'd need to wire up viewporter).
since wayland doesn't provide a touch id in cancel events, track what
points are active so we can cancel all of them
timestamp is also not provided - use 0 because no one's paying attention
to that anyway
