-uninstalled.pc files are a pkg-config facility for working with

With pkg-config, foo-uninstalled.pc overrides foo.pc. foo-uninstalled.pc
should never be installed, and will be generated with references to the

If you set up your environment so pkg-config looks for .pc files in your

you haven't installed with "make install".
This can save time and space over installing with a prefix.

Damage coordinates are in global coordinate space, and they need to
be translated to local coordinate space so multiple outputs can work.
This path now matches the similar path in the X11 backend.
This patch fixes the appearance of multiple windows in the parent
compositor. Previously, all windows except the one with nested output
position 0,0 would have their damage for the parent wl_surface always
fall outside of the wl_surface, save the decorations which were handled
separately. If the parent compositor was Weston/GL, this would lead to
the output area remaining black as partial GL texture uploads would
practically never update the texture. If the parent compositor was
Weston/pixman, the parent windows would not update on screen unless
something else caused the area to be repainted.

The wayland-backend with --sprawl is one way to trigger
wayland_output_create_for_parent_output(), which intends to find a mode
from the parent mode list and use it. Calling wayland_output_set_size()
initialized an embedded struct weston_mode and inserts that into the
mode list. Then the assignment output->mode = *mode; corrupts the
mode_list by overwriting the link entry. This leads to an endless loop
in bind_output() in compositor.c.
Fix this by manually doing the setup that wayland_output_set_size() did
and do not call it.
As a side effect, it now relays the parent compositor's physical output
size to our own clients. It no longer smashes the refresh rate either.

Calling wl_display_roundtrip() from within a Wayland event handler means
we will re-enter event dispatch, that is, it will lead to recursive
dispatch. Even if libwayland-client was safe, this would lead to
unexpected code paths: the first event handler function has not returned
when other event handler functions may get called. In this particular
case it maybe didn't hurt, but it's still a fragile pattern to use.
Replace the wl_display_roundtrip() with a manual sync callback to do the
work.
This does not break the wayland-backend initialization sequence, because
sprawl_across_outputs was set only after the roundtrip to ensure
wl_registry globals have been received so the code would not have been
hit anyway, and weston_backend_init() also has a second roundtrip that
ensures the per wl_output events have been received before continuing.
For wayland-backend output hotplug the change is insignificant because
it will only delay the output creation a bit, and the parent outputs are
not processed anywhere in between.

compositor-wayland.c is strange in

wayland_output_set_size() that initialized the mode list with a single
mode manufactured from width and height and set that mode as current.
Then it continued to reset the mode list and adding the list of modes
from the parent output, leaving the current mode left to point to a mode
struct that is no longer in the mode list and with a broken 'link'

Use EGL fence sync objects to emit timepoints for the beginning and the

using the sync file fds associated with the fence sync objects. The sync
file fds are acquired using the facilities provided by the
EGL_ANDROID_native_fence_sync extension.
The asynchronous timepoint submissions are stored in a list in
gl_output_state until they are executed, and any pending submissions
that remain at output destruction time are cleaned up.
If timelining is inactive or the required EGL extensions are not

Note that the GPU timestamps returned by sync files are in the
