After cancelation we destroy the touch points associated with this
surface as the Wayland spec says:
No further events are sent to the clients from that particular gesture.
Touch cancellation applies to all touch points currently active on this
client's surface. The client is responsible for finalizing the touch
points, future touch points on this surface may re-use the touch point
ID.

This function sidesteps damage tracking and output awareness on
buffers/surfaces. This function isn't a great fit for the API.
Let's also inline the function and simplify it.
There were a couple places this was missing
- on mode change of an output. If the resolution changes for example
nodes may fall out of the view.
- on commits on an output for scale or transform changes
- when the transform of a buffer is changed. If the dest size is not
set, the buffer may have been rotated potentially changing its size
if the buffer width != height
With protocol additions such as [1], compositors currently have no
way to opt out of the version upgrade. The protocol upgrade will
always be backwards-compatible but may require new compositor
features.
The status quo doesn't make it possible to ship a protocol addition
without breaking the wlroots API. This will be an issue for API
stabilization [2].
To address this, let compositors provide a maximum version in the
function creating the global. We need to support all previous versions
of the interface anyways because of older clients.
This mechanism works the same way as Wayland clients passing a version
in wl_global.bind.

Maintaining our internal table up-to-date is tedious: one needs to
manually go through the PnP ID registry [1] and check whether we're
missing any entry.
udev_hwdb already has an API to fetch a manufacturer name from its
PnP ID. Use that instead.

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.
The original commit introduced a bug by transposing the order of
some of the fields in xcb_size_hints_t. Since XCB ICCCM support is
required now, we can just eliminate the duplicate structs.
With minor changes:
- Remove #ifdef HAS_XCB_ICCCM guards
- Fix #includes
- Fix references to local size_hints struct
This reverts commit 12b9b1a4bd.
