In Wayland, window configuration is asynchronous. Window geometry is
constrained, the constrained geometry is sent to the client, and the
client will adapt its surface and acknowledge the configuration. When
acknowledged, we shouldn't reconstrain again, as that may invalidate the
constraint calculated for the configured size.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/907
Historically, wl_shell clients used to pretend the input region was
equivalent to the window geometry, so for "correctness" lets do that
here too. This makes wl_shell clients with drop shadow behave marginally
better than before.

This moves the cached subsurface surface state into the generic
MetaWaylandSurface namespace. Eventually it'll be used by other surface
roles which as well aim to implement synhcronization.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/907
The name didn't communicate it was about surface state, and it somewhat
confusingly had the name "pending" in it, which could be confused with
the fact that while it's used to collect pending state, it's also used
to cache previously committed pending state.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/907
With the eventual aim of exposing the internals of MetaWaylandSurface
outside of meta-wayland-surface.c, make users of the pending state use a
helper to fetch it. While at it, rename the struct field to something
more descriptive.

The intention of meta_window_wayland_move_resize() is to finish a
move-resize requested previously, e.g. by a state change, or a
interactive resize. Make the function name carry this intention, by
renaming it to meta_window_wayland_finish_move_resize().
https://gitlab.gnome.org/GNOME/mutter/merge_requests/907
Presumably this function is supposed to be like
meta_kms_impl_simple_handle_page_flip_callback() but the condition in the
if-statement is inverted. Fix the inversion to make these two functions look
alike.
This is part 2 of 2 fixing a complete desktop freeze when drmModePageFlip()
fails with EINVAL and the fallback to drmModeSetCrtc() succeeds but the success
is not registered correctly as completed "flip". The freeze occurs under
wait_for_pending_flips() which calls down into meta_kms_impl_device_dispatch()
which ends up poll()'ing the DRM fd even though drmModeSetCrtc() will not
produce a DRM event, hence the poll() never returns. The freeze was observed
when hotplugging a DisplayLink dock for the first time on Ubuntu 19.10.
This patch makes meta_set_fallback_feedback_idle() actually end up calling into
notify_view_crtc_presented() which decrements
secondary_gpu_state->pending_flips so that wait_for_pending_flips() can finish.

mode_set_fallback() schedules a call to mode_set_fallback_feedback_idle(), but
it is possible for Mutter to repaint before the idle callbacks are dispatched.
If that happens, mode_set_fallback_feedback_idle() does not get called before
Mutter enters wait_for_pending_flips(), leading to a deadlock.
Add the needed interfaces so that meta_kms_device_dispatch_sync() can flush all
the implementation idle callbacks before it checks if any "events" are
available. This prevents the deadlock by ensuring
mode_set_fallback_feedback_idle() does get called before potentially waiting
for actual DRM events.
Presumably this call would not be needed if the implementation was running in
its own thread, since it would eventually dispatch its idle callbacks before
going to sleep polling on the DRM fd. This call might even be unnecessary
overhead in that case, synchronizing with the implementation thread needlessly.
But the thread does not exist yet, so this is needed for now.

When rendering on-stage, it might be necessary to push offscreen
framebuffers to the paint context by external consumers, such as
GNOME Shell effects.
Expose clutter_paint_context_push|pop_framebuffer().
https://gitlab.gnome.org/GNOME/mutter/merge_requests/955
This means CoglContext is now also introspected, although its
constructor and some getters are skipped to avoid having to expose even
more types. This makes it possible to create pipelines using Javascript.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/935
They have been deprecated for a long time, and all their uses in clutter
and mutter has been removed. This also removes some no longer needed
legacy state tracking, as they were only ever excercised in certain
circumstances when there was sources (pipelines or materials) on the now
removed source stack.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/935
This means cogl_set_source_color*() that switches to the opaque or
blending pipeline, or cogl_source_set_texture() which switches to the
texture pipeline.
Left is the opaque pipeline, as it is still used to compare other
pipelines to check whether they are opaque or not, and as the default
pipeline still pushed to the source stack during initialization.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/935
Change the warp modes test to sanity check CoglPrimitive based polygon
drawing instead of cogl_polygon(). This removes some checks, as
cogl_polygon() has explicitly documented special behaviour for automatic
wrap modes, which CoglPrimitive does not.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/935
Stop using API that uses the implicit Cogl framebuffer stack, (e.g.
cogl_push_matrix()) and replace usage by the corresponding API taking an
explicit framebuffer (e.g. cogl_framebuffer_push_matrix()).
For offscreens etc, the offscreen framebuffer is still pushed to and
popped from the Cogl framebuffer stack, so that paint nodes still draw
to the right framebuffer.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/935
While we still push and pop to the Cogl framebuffer stack, as so is
still needed to render the actors correctly, don't use the API using the
implicit framebuffer stack ourself in the offscreen effect code.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/935
Instead of using cogl_polygon(), which uses deprecated API, implement
polygon drawing using the CoglPrimitive API family. While the test might
have been used to explicitly test cogl_polygon() it could still be
useful to test the non-deprecated way of rendering polygons.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/935
Port tests to use API such as cogl_framebuffer_push_matrix() instead of
cogl_push_matrix() all over the Clutter tests, with one exception:
cogl_polygon(). It'll be ported over in a separate commit, as it is less
straight forward.
Implicitly set CoglMaterial properties are changed to explicitly created
and destructed CoglPipelines with the equivalent properties set.
cogl_push|pop_framebuffer() is replaced by explicitly passing the right
framebuffer, but tests still rely on cogl_get_draw_framebuffer() to get
the target framebuffer.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/935
clutter_paint_node_get_framebuffer() fell back on
cogl_get_draw_framebuffer() when the root node didn't have a custom
get_framebuffer vfunc. As this relies on deprecated implicit Cogl stack
API, it needs to go away, so handle this in the caller that knows more
about the context.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/935
Instead of using the intermediate stage state "active framebuffer" to
find the framebuffer a paint eventually targets, use the "base
framebuffer" of the paint context, as this more correctly corresponds to
the end point of a paint. It also means we can then later remove this
intermediate state from the stage.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/935
Instead of pushing and popping the Cogl framebuffer stack, use the
framebuffer passed around using the pick context. This removes usage of
the deprecated framebuffer stack when picking.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/935
Rendering off stage we never cull, and previously this was checked by
comparing the "active framebuffer" of the stage, to the current
framebuffer in the cogl stack. Replace this by checking whether the
current paint context is currently drawing on stage or not.
