Makes it easier to figure out why a backend/renderer is picked.

Allow wlr_buffer_impl.get_data_ptr to return a format.
This allows the Pixman renderer to not care about get_dmabuf/get_shm,
and only care about get_data_ptr. This will also help with [1], because
client wl_shm buffers can't implement get_shm.

This reverts commit f9f90b417366581b58d806956c9b2099417ed4b3.
gbm_bo_get_modifier may return a modifier in these cases:
- The kernel doesn't support modifiers but Mesa does
- WLR_DRM_NO_MODIFIERS=1 is set
However, in both of these cases, the gbm_bo has been allocated
without modifiers.
There is already a check in drm_fb_create for modifiers:
wlr_drm_format_set_has will make sure buffers with an explicit
modifier will be rejected if the DRM backend doesn't support them.
So no need for an additional check in get_fb_for_bo.

On GPU unplug, disabling a CRTC can fail with EPERM.

Any use of the DRM FD after the remove event results in a "Permission
denied" error.

The previous code would always print "falling back to legacy method",
even if the format wasn't ARGB8888.
Drop get_fb_for_bo_legacy, since the code can just be inlined without
hurting readability.
Ideally we should only fallback to drmModeAddFB if the error code
indicates the BE failure, but the original PR [1] doesn't say what
error code is returned by the kernel.

We shouldn't strip a modifiers from buffers, because the will make
the kernel re-interpret the data as LINEAR on most drivers,
resulting in an incorrect output on screen.

Stop listing all available cursors each time a cursor theme is
loaded. They can be obtained from the CLI instead, e.g.
ls /usr/share/icons/Adwaita/cursors

Prior to this commit, WLR_RENDERER was only looked up when the
backend returned a DRM FD.
Make it so WLR_RENDERER is always looked up, so that running wlroots
on a system without a GPU and with WLR_RENDERER=gles2 fails as
expected instead of falling back to the Pixman renderer.

GitHub refuses to render ircs:// URLs.

Switch from the pkg-config dependency names to the upstream
libxcb repository names. Each repository contains multiple
libraries but is generally available in distributions as a single
package.
libxcb contains xcb, xcb-composite, xcb-xfixes, xcb-xinput and
xcb-shm. libxcb-render-util contains xcb-render. libxcb-wm
contains xcb-icccm. xcb-image was outdated and is no longer needed.

We already get the PID from XRes and _NET_WM_PID code can overwrite it
with incorrect data.
|
|
`_NET_WM_PID` is unreliable: it is optional and even if set it may
contain PIDs from sandbox namespaces or remote systems.
Prefer XRes v1.2 QueryClientIds method which returns PIDs as seen by the
Xwayland server.

The NULL check already exists in wlr_texture_destroy, no need to
duplicate it in each impl

We were leaking wlr_pixman_buffers and a wlr_drm_format_set.

This fixes a crash when calling wlr_output_test() on a headless
output.

Make it clear GLES2 is being used. Before this commit, various
GL-related information was printed, but not an easy-to-find line
about which renderer is being picked up.
|
|
This env var forces the creation of a specific renderer. If no renderer
is specified, the function will try to create all of the renderers one
by one until one is created successfuly.

This examples uses `wlr_render_quad_with_matrix` to render coloured
squares on the screen, and uses the rotation to make them spin on their
middle.

Previously, the same struct was used for linux-dmabuf-v1 params
and buffer. This made the whole logic a little bit awkward, because
a wlr_dmabuf_v1_buffer could either be still being constructed, or
be a complete buffer.
Introduce a separate wlr_linux_buffer_params_v1 struct for buffer
params still being constructed. Once the params are complete (ie.
once the create request is sent), the params struct is destroyed
and the buffer struct is created.
This will help with [1] as well.

Drop wlr_dmabuf_v1_buffer_from_params_resource and
wlr_linux_dmabuf_v1_from_resource. Contrary to wl_buffer, these
resources are internal linux-dmabuf-v1 implementation details and
should not be shared with other interfaces.

If a NULL xkb_rule_names pointer is passed to
xkb_keymap_new_from_names, libxkbcommon will default to reading
the XKB_* env variables. So there's no need to do it ourselves.
Also s/xkb_map_new_from_names/xkb_keymap_new_from_names/ since the
latter is more consistent with the returned struct name.

Most of the examples had a GLES2 dependency, but weren't using it.
Convert multi-pointer to wlr_renderer instead of using directly
glClear.

This was lost in the session_impl removal refactor.

Allow selecting whether the GLES2 renderer gets enabled.
