f07af89f9c libweston: Move output damage subtraction out of backends
Right now every backend clears output damage from the primary plane when
it repaints. Instead of having this same operation spread across all
the backends, just do it in the core instead.

In the future, we want to remove damage tracking from the primary plane
entirely, and this is a small step in that direction.

Turn the Pixman/GL if/else conditionals into switch cases to make it
easier to add support for other renderers in the future.

Also makes sure that weston --backend=wayland --renderer=noop fails

90c11cf40e libweston: move weston_compositor_shutdown call out of backends
If we want to support multiple backends, the compositor must take care
to call this once, at the appropriate moment, so stop letting the
backends handle compositor shutdown themselves.

Move the weston_compositor_shutdown() calls from the backend::destroy
callbacks into weston_compositor_destroy() and the calls in the backend
creation error paths into weston_compositor_load_backend().

7d2112c713 libweston: pass backend to weston_windowed_output_api::create_head()
Pass the backend instead of the compositor to the windowed output API

That way the backend will not have to find the backend pointer from the

6b23ffabcf backend-wayland: immediately unref the renderbuffer for use shm buffers
wayland_output_destroy_shm_buffers() is called immediately before
output_destroy() of the renderer is called. And for the pixman renderer all
renderbuffers must be destroyed before the output can be destroyed.
Also, weston_renderbuffer_unref() is not called when the buffer is released
because buffer->output is now NULL, so the renderbuffer would be leaked.

So just unref the renderbuffer immediately. Set it to NULL to avoid unreffing it
again should wayland_output_destroy_shm_buffers() be called again before the
buffer is released. This can happen during an xdg-shell resize.

8636422309 libweston: add weston_renderer::resize_output()
Previously renderers were not told when the output (framebuffer they
need to draw) size changed. Renderers just pulled that information out
from weston_output::current_mode when they happened to need it. This
makes some things awkward, like resizing the shadow or intermediate
buffers. In fact, Pixman-renderer does not even support resizing its
shadow buffer, nor does GL-renderer. DRM-backend has to destroy and
re-create the renderer output state anyway, but rdp, x11 and wayland
backends would be natural users of resizing API.

This commit adds an API for resizing with empty implementations. Actual
implementations will be added in following patches for each renderer
while moving parts of resizing code from backends into the renderers.
No-op renderer needs no implementation.

Only wayland-backend has actual resizing code already, and that is made
to call the new API. Unfortunately, Pixman and GL renderers differ: one
does not blit them while the other does. In order to assert the
functionality of each renderer to keep the API consistent,
wayland-backend needs to lie to pixman-renderer. That's not new, it
already does so in wayland_output_get_shm_buffer() where the 'pm_image'
addresses only the interior area instead of the whole buffer.

d4eafbaa98 backend-wayland: fix pixman buffer size
As wayland-backend is blitting the output decorations into the output
buffer itself, it pretends towards the pixman-renderer that there is no
decorations area. The pixman_image_create_bits() call wraps the
previously allocated buffer with an offset so that pixman-renderer will
paint in the right position.

The bug is that this pixman image was using the original buffer width
and height, instead of the composited area width and height. So the
pixman image looks too big to pixman-renderer, but the renderer didn't
care. The image being too big does risk access out of bounds in
pixman-renderer.

I found this when I was making renderers explicitly aware of the
frambuffer size and resizing, added asserts, and they surprisingly
failed. This fixes that.

6ee6e76a0c compositor: remove repaint_data from compositor
The repaint_data is entirely backend specific. Moreover, it is only used by the
drm backend, while other backends ignore the repaint data.

There will always be only one repaint active, thus, there is no need to pass the
repaint data from the outside.

The repaint_data breaks with the multi-backend series, which calls repaint begin
for all backends to get the repaint_data. The repaint_data of the last backend
will then be passed to all other backend. At the moment, this works, because the
drm backend is the only backend that implements the begin_repaint call.

Another option would be to track the repaint data per backend in the compositor,
but actually, it the backend needs to track state across the calls, it's its own
responsibility.
