c228e23b05 configure.ac: Enable AC_USE_SYSTEM_EXTENSIONS
AC_USE_SYSTEM_EXTENSIONS enables _XOPEN_SOURCE, _GNU_SOURCE and similar
macros to expose the largest extent of functionality supported by the
underlying system.  This is required since these macros are often
limiting rather than merely additive, e.g. _XOPEN_SOURCE will actually
on some systems hide declarations which are not part of the X/Open spec.

Since this goes into config.h rather than the command line, ensure all
source is consistently including config.h before anything else,
including system libraries.  This doesn't need to be guarded by a
HAVE_CONFIG_H ifdef, which was only ever a hangover from the X.Org
modular transition.

1cc5ac34b5 clients: Nested compositor example
A wayland compositor doesn't provide a mechanism for buffer sharing between
clients.  Under X, one client can render to a Pixmap and another can use it
as a source in a subsequent drawing operations.  Wayland doesn't have a
mechanims to share Pixmaps or textures between clients like that, but it's
possible for one client to act as a nested compositor to another client.

This less work than it sounds, since the nested compositor won't have to
provide input devices or even any kind of shell extension.  The nested
compositor and its client can be very tightly coupled and have very specific
expectations of what the other process should provide.

In this example, nested.c is a toytoolkit application that uses cairo-gl
for rendering and forks and execs nested-client.c.  As it execs the client,
it passes it one end of a socketpair that will be the clients connection
to the nested compositor.  The nested compositor doesn't even create a
listening socket.

The client is a minimal GLES2 application, which just renders a spinning
triangle in its frame callback.

79346ab3a5 shell: wait for desktop-shell init before fade in
On Raspberry Pi, weston-desktop-shell is so slow to start, that the
compositor has time to run the fade-in before the wallpaper is up. The
user launching Weston sees the screen flipping to black, the fbcon
fading in, and then the desktop popping up.

To fix this, wait for the weston-desktop-shell to draw
everything before starting the initial fade-in. A new request is
added to the private desktop-shell protocol to signal it. If a
desktop-shell client does not support the new request, the fade-in
happens already at bind time.

If weston-desktop-shell crashes, or does not send the 'desktop_ready'
request in 15 seconds, the compositor will fade in anyway. This should
avoid a blocked screen in case weston-desktop-shell malfunction.

shell_fade_startup() does not directly start the fade-in but schedules
an idle callback, so that the compositor can process all pending events
before starting the fade clock. Otherwise (on RPi) we risk skipping part
of the animation. Yes, it is a hack, that should have been done in
window.c and weston-desktop-shell instead.

surface has a buffer_transform or a buffer_scale. To fix this we pass
the transform and scale into the toysurface prepare and swap calls and

Without this interactive resize on the top or left sides of a transformed

9777744cda window: avoid a gcc warning in buffer release handler
Apparently some compilers complain about set but not used variables
'available' and 'bufs', but I don't get the warning. Still, separate the
debugging code from shm_surface_buffer_release(), so that we only
compute 'bufs' when it is printed. This should fix the warnings.

The debugging code now prints the shm_surface buffer state before and
after, instead of just after.

a50e6e4c50 config-parser: Honor XDG_CONFIG_DIRS
This set of changes adds support for searching for a given config file
in the directories listed in $XDG_CONFIG_DIRS if it wasn't found in
$XDG_CONFIG_HOME or ~/.config.  This allows packages to install custom
config files in /etc/xdg/weston, for example, thus allowing them to
avoid dealing with home directories.

To avoid a TOCTOU race the config file is actually open()ed during the
search.  Its file descriptor is returned and stored in the compositor
for later use when performing subsequent config file parses.

eebff54c03 window: throttle resizing to the main surface
In case a toytoolkit application manages to schedule resizes constantly,
throttle them to the main surface display.

When resizing, all surfaces are updated synchronously, so it also makes
sense to synchronize on the main surface's frame callback particularly.
Rendering any faster will not make sense.

e9297f8e7e window: prevent EGL sub-surface deadlock
Mesa's eglSwapBuffers() waits for the frame event from the previous
swapBuffers, before it returns. Apparently eglSwapInterval(), which
should be able to disable the wait, is unimplemented for now.

When a sub-surface contains an EGL widget, and the commit mode is
synchronized, the frame events will not be delivered to EGL until the
parent surface gets committed. Therefore rendering the EGL widget twice
would lead to a deadlock.

When the window is being resized, we need to force a repaint of the EGL
widget, too, to make the whole window consistent. For that, we need to
make sure the frame event from the previous eglSwapBuffers() actually
arrives.

This patch adds an extra wl_surface.commit(parent), when the window is
being resized, which should guarantee, that the previous eglSwapBuffers
gets its event.

To properly handle an EGL widget in a sub-surface, running in its own
thread, the EGL widget's automatic updates should be paused before
sending the extra wl_surface.commit(parent). A natural place for the
pause would be in the widget's resize hook. However, wl_surface.commit
cannot be called right after resize hooks, because it would commit new,
incomplete surface state. Therefore this patch is not enough for
threaded toytoolkit applications.  Luckily those do not exist yet.

When eglSwapInterval() gets implemented, this patch should be reverted.

7ff7a80007 clients: add subsurfaces demo
Add a demo program with:
- a main surface (green)
- a Cairo-image sub-surface (red)
- a raw GLESv2 widget (triangle)

Sub-surface input region is set empty to avoid problems in toytoolkit.

If Cairo links to libGL, then we will end up with also libGLESv2 linked
to subsurfaces program, and both libs getting really used, which leads
to disaster.

Do not build subsurfaces demo, if Cairo links to libGL and cairo-egl is
usable.

The GL rendering loop is not tied to the toytoolkit or the widget, but
runs directly from its own frame callback. Therefore it runs
independent of the rest of the application. This also relies on one of
two things:
- eglSwapInterval(0) is implemented, and therefore eglSwapBuffers never
  blocks indefinitely, or
- toytoolkit has a workaround, that guarantees that eglSwapBuffers will
  return soon, when we force a repaint on resize.
Otherwise the demo will deadlock.

The code is separated into three sections:

1. The library component, using only EGL, GLESv2, and libwayland-client
   APIs, and not aware of any toolkit details of the parent application.
   This runs independently until the parent application tells otherwise.

2. The glue code: a toytoolkit application widget, who has its own
   rendering machinery.

3. The application written in toytoolkit.

This patch also adds new toytoolkit interfaces:
- widget_get_wl_surface()
- widget_get_last_time()
- widget_input_region_add()

Toytoolkit applications have not had a possibility to change the input
region. The frame widget (decorations) set the input region on its own
when used, otherwise the default input region of everything has been
used. If a window does not have a frame widget, it can now use
widget_input_region_add() to set a custom input region.

These are not window methods, because a widget may lie on a different
wl_surface (sub-surface) than the window.

Changes in v3:
- replace set_commit_mode with set_sync and set_desync

40cb67b2ac window: implement per-surface redraws
Add redraw_needed flag to all surfaces, in addition to having one in
window. The window redraw_needed flag is changed to force a redraw of
the whole window, regardless of frame events.

widget_schedule_redraw() now schedules the redraw only for the surface,
where the widget is on. window_schedule_redraw() is equivalent to
scheduling a redraw for all (sub-)surfaces of the window.

We still use only one deferred task for all redraws.

surface_redraw() will skip the redraw, if the window does not force a
redraw and the surface does not need a redraw. It will also skip the
redraw, if the frame callback from the previous redraw has not triggered
yet. When the frame callback later arrives, the redraw task will be
scheduled, if the surface still needs a redraw.

If the window forces a redraw, the redraw is executed even if there is a
pending frame callback. This is for resizing: resizing should trigger a
window repaint, as it really wants to update all surfaces in one go, to
apply possible sub-surface size and position changes. Resizing is the
only thing that makes a window force a redraw.

With this change, subsurfaces demo can avoid repainting the cairo
sub-surface while still animating the GL sub-surface.

35e82631b6 window: create sub-surfaces
The new application API window_add_subsurface() will create a plain
widget that is on a new sub-surface.

The sub-surface position is taken from the surface's root widget
allocation. This way widget allocations are always in the main surface
(i.e. window) coordinates. However, Cairo drawing coordinates will now
be different to widget coordinates for sub-surfaces. Cairo coordinates
are fixed by applying a translation in widget_cairo_create(), so that
widget drawing code can simply use the widget allocation as before.

Sub-surfaces are hooked up into resize, window flush, redraw, and
find_widget. Window maintains a list of sub-surfaces in top-first order.

Add a client settable default commit mode, and toggle the mode when
resizing to guarantee in-sync updates of a window and its sub-surfaces.

- replaced set_commit_mode with set_sync and set_desync

aef0254dd5 window: implement shm triple-buffering
Increase the maximum number of shm "leaves" to three, and rewrite the
leaf release and pick algorithms. The new algorithms hopefully improve
on buffer re-use while freeing unused buffers.

The goal of the new release algorithm is to always leave one free leaf
with storage allocated, so that the next redraw could start straight on
it.

The new leaf picking algorithm will prefer a free leaf that already has
some storage allocated, instead of just picking the first free leaf that
may need to allocate a new buffer.

Triple-buffering is especially for sub-surfaces, where the compositor
may have one wl_buffer busy on screen, and another wl_buffer busy in the
sub-surface cached state due to the synchronized commit mode. To be
able to forcibly repaint at that situation for e.g. resize, we need a
third buffer.

2396aec684 protocol: add sub-surfaces
Add protocol for sub-surfaces, wl_subcompositor as the global interface,
and wl_subsurface as the per-surface interface extension.

This patch is meant to be reverted, once sub-surfaces are moved into
Wayland core.

Changes in v2:

- Rewrite wl_subcompositor.get_subsurface description, and move mapping
  and commit details into wl_subsurface description. Check the wording
  in wl_subsurface.set_position description.

- Add wl_subsurface.set_commit_mode request, and document it, with the
  commit_mode enum. Add bad_value error code for wl_subsurface.

- Moved the protocol into Weston repository so we can land it upstream
  sooner for public exposure. It is to be moved into Wayland core later.

- Add destroy requests to both wl_subcompositor and wl_subsurface, and
  document them. Experience has showed, that interfaces should always
  have a destructor unless there is a good and future-proof reason to not
  have it.

Changes in v3:

- Specify, that wl_subsurface will become inert, if the corresponding
  wl_surface is destroyed, instead of requiring a certain destruction
  order.

- Replaced wl_subsurface.set_commit_mode with wl_subsurface.set_sync and
  wl_subsurface.set_desync. Parent-cached commit mode is now called
  synchronized, and independent mode is desynchronized. Removed
  commit_mode enum, and bad_value error.

- Added support for nested sub-surfaces.
