With the idle_inhibit optimization, wlsc_compositor_wake() is a no-op if
idle_inhibit > 0.
When the shell is waking up the compositor from SLEEPING state as an
indirect response to input activity, it does not work. The call path is:
notify_key() / notify_button()
wlsc_compositor_idle_inhibit()
wlsc_compositor_activity()
shell->unlock()
send prepare_lock_surface event
idle_inhibit++
and when the desktop-shell client responds to the event:
desktop_shell_set_lock_surface() / desktop_shell_unlock()
wlsc_compositor_wake()
no-op, because idle_inhibit > 0
Fix this by removing the idle_inhibit check from wlsc_compositor_wake().
The optimization did not work for pointer motion while no keys pressed,
anyway, so the performance hit is probably unobservable.
Now the compositor wakes up also on key or button press.

When compositor enters SLEEPING state, the shell plugin goes locked. If
compositor wakes up itself, it will fade in while the shell may not yet
have a lock surface to show.
Fix this by assigning wake-up to be called from the shell, if the
compositor is SLEEPING. The shell may wait for the lock surface request,
and only then wake up the compositor. The compositor will fade in
directly to the lock screen.

Add protocol and functions for supporting screen locking, triggered by
activity timeout.
After activity timeout, compositor starts the fade to black, and then
enters SLEEPING state. At that point it calls lock() in the shell
plugin.
When input events trigger a wakeup, unlock() in the shell plugin is
called. This sends prepare_lock_surface event to the desktop-shell
client. The screen stays locked while the compositor starts fade-in.
At this point, desktop-shell client usually creates a surface for the
unlocking GUI (e.g. a password prompt), and sends it with the
set_lock_surface request. The compositor supposedly shows and allows
interaction only with the given lock surface (not yet implemented).
When desktop-shell has authenticated the user, or instead of issuing
set_lock_surface, it sends the unlock request. Upon receiving the unlock
request, the shell plugin unlocks the screen.
If desktop-shell client dies, the screen is unlocked automatically.

This is just a cosmetic change, because 'resource' happens to be the

This is the same as the damage of the top-level surface so just use that.
There's a problem that if we change the stacking, the damage layering breaks,
but that's a problem we already have.
The shell module only needs to deal with attach when it's either the initial
attach or when the attach changes the size of the surface. In case of
initial attach, the shell needs to pick a position for the surface and a
place in the surface stack. We split this case out as a new shell->map
callback. The other case is split into the shell->configure callback,
where the shell may adjust the surface position or reject the new size.
The third parameter of open() is for file-creation modes. File flags are passed
in the second paramater.

Check, that only the desktop-shell client spawned by the compositor
(desktop-shell plugin) is allowed to bind to desktop_shell interface.
Other clients will receive an error like:
wl_display@1.error(desktop_shell@20, 0,
"permission to bind desktop_shell denied")
The error has the proper object id and interface type.
Note: desktop-shell cannot be started manually anymore, it has to be
started by the compositor automatically.

Fork and exec desktop-shell in the compositor. This is a way to create
an authenticated client. Later, the desktop-shell interface will be
reserved for this client only.
For exec to work, the compositor should be started from the
wayland-demos' root directory.

The repaint logic breaks when finish_frame is called from the present
callback. Ideally we should throttle to vsync (or even better, the
compositor repaint cycle, but hey, X is X), but this goes a long way.
The drm compositor always creates a 64x64 bo for the cursor image
regardless of the size of the actual cursor. When the fade animation
kicks in it disables the hardware cursor so that it is rendered as a
regular surface. This surface is rendered to a 32x32 region but using
a 64x64 texture so the cursor gets scaled down.
Fix this by making create_cursor_image return the actual size of the
image created to the compositor.

wlsc_output_repaint may call wlsc_surface_damage indirectly through
wlsc_output_set_cursor. If this happens in the call made from repaint,
one ends up with repaint being called from both idle_repaint and
wlsc_output_finish_frame.
Fix this by setting output->repaint_scheduled to 1 before calling
wlsc_output_repaint in the function repaint.
[krh] Edited to just only clear repaint_scheduled, when we no longer have
a repaint scheduled.

On repaint, wlsc_output_repaint will replace output->scanout_buffer with
the new front buffer and then output->present() will cause this buffer
to be displayed. When wlsc_output_finish_frame is called, the
compositor will send a release buffer event for output->scanout_buffer
which is actually the front buffer now.
This patch changes this code to release the previous scanout_buffer
instead of the front buffer on wlsc_output_finish_frame.

This isn't going to change over time, so just tracking it in the
evdev device is a little easier. Also, we need to adjust for the
output position when transforming the device events to screen space.
The compositor was never actually calling the output backend to turn off
the hardware cursor when the screen begins fading. This would result in
a stuck hardware cursor and movable software cursor for the duration of
the fade/unfade.

Adds a general wlsc_compositor_shutdown() function that all output
backends call when shutting down. wlsc_compositor_shutdown() will call
a new 'destroy' method of each output to perform backend-specific
cleanup (e.g., turning off the hardware cursor in the DRM compositor).

The bo for the cursor image is always created with size 64x64 even if
the actual cursor image is smaller than that. If this memory is not

- Fixes segfault, if first enumerated connector is not connected.
- Corrects x-offset where e.g. the 2. of 3 connectors is not connected.
(where width of 1. output would have taken twice as
offset for output at 3. connector)

This reverts cde9bfc805. We need to damage the
area covered by the old surface when attaching a new buffer. The new surface
area will be damaged by the client.
I may have missed something, but - since the Wayland compositor
already picks a platform backend, opens a connection and initializes the
backend specific display data structure it doesn't make sense
to let egl pick a platform. If it picks a different one the
display specific data structure will most likely not match.
Thus determine the platform in the Wayland rendering backend by setting
the EGL_PLATFORM env variable.
For the client any other platform than 'wayland' doesn't seem to make
sense.
I'm not sure if I've got the the platform ofr openfwd right.

The shell module is responsible for implementing the higher level
compositor behavior. We default to the desktop-lite shell built in to
the compositor.
Instead of having a separate check function, we just mark our x11 event
source as needing a post-dispatch check. The event loop will call our
dispatch function again after all dispatching is done, this time with
mask = 0. If we don't process any events, return 0, so the event loop
doesn't keep calling us.
If somebody else did an X11 round trip, that could leave events in the
XCB buffer that we wouldn't see until the next X event came in. The new
event source check function lets us check the XCB queue after dispatching
and this way we'll see events we need to deal with right away.
The event handling gets a little trickier this way but we need the
keymap sent immdiately after the focus_in event to determine which keys
are pressed as the compositor receives keyboard focus.
We need to look at the focus_in and keymap notify pair to correctly determine
the set of held down keys at focus in time, so generalize the handling
of event pairs in preparation for that.
