Valgrind has shown that in at least one place (default_grab_pointer_focus)
we're testing uninitialized values coming out of weston_compositor_pick_view.
This is happening when default_grab_pointer_focus is called when there is
nothing on the view list, and during the first repaint when only the black
surface with no input region exists.
This patch adds a function to clear pointer focus and also set the sx,sy
co-ordinates to a sentinel value we shouldn't compute with.
Assertions are added to make sure any time pointer focus is set to NULL
these values are used.
weston_compositor_pick_view() now returns these values too.
Now the values are always initialized, even when no view exists, and
they're initialized in such a way that actually doing computation
with them should fail in an obvious way, but we can compare them
safely for equality.

Going from seat to input device requires that we test the device
before relying on the pointer. In all of these binding functions
we can trust exactly one input device type directly. If we pass
that in instead of a seat it's more obvious that we can trust
the one pointer we have.
When a seat is required, we can access through the device we have
and use that to get to other device types for the seat, provided
we validate them appropriately.

guaranteed that the seat has a device of that type. If we pass in
that type instead of the seat, it's obvious we don't have to test it.
The bindings can still get the seat pointer via whatever->seat if they
need it.

Looking at the first of these, unbind_input_panel() gets called when the
text-backend destroys its helper client which has bound to input_panel
interface. This happens after the shell's destroy_signal callback has
been called, so the shell has already been freed.
The other two errors come from
wl_list_remove(&input_panel_surface->link);
which has gone stale when the shell was destroyed
(shell->input_panel.surfaces list).
Rather than creating even more destroy listeners and hooking them up in
spaghetti, modify text-backend to not hook up to the compositor destroy
signal. Instead, make it the text_backend_init() callers' responsibility
to also call text_backend_destroy() appropriately, before the shell goes
away.
This fixed all the above Valgrind errors, and avoid a crash with
ivi-shell when exiting Weston.
Also using desktop-shell exhibited similar Valgrind errors which are
fixed by this patch, but those didn't happen to cause any crashes AFAIK.

This timer delays the output_repaint towards the end of the refresh
period, reducing the time from repaint to present.
The length of the repaint window can be set in weston.ini.
The call to weston_output_schedule_repaint_reset() is delayed by one
more period. If we exit the continuous repaint loop (set
output->repaint_scheduled to false) in finish_frame, we may call
start_repaint_loop() unnecessarily. The problem case was actually
observed with two outputs on the DRM backend at 60 Hz, and 7 ms
repaint-window. During a window move, one output was constantly falling
off the continuous repaint loop and introducing additional one frame
latency, leading to jerky window motion. This code now avoids the
problem.
Changes in v2:
- Rename repaint_delay_timer to repaint_timer and
output_repaint_delay_handler to output_repaint_timer_handler.
- When computing the delay, take the current time into account. The timer
uses a relative timeout, so we have to subtract any time already gone.
Note, that 'gone' may also be negative. DRM has a habit of predicting
the page flip timestamp so it may be still in the future when we get the
completion event.
- Do also a sanity check 'msec > 1000'. In the unlikely case that
something fails to provide a good timestamp, never delay for more than
one second.

Add API for setting a clip ('scissor' in the code) rectangle per view,
in surface coordinates. Ivi-shell requires this feature to be able to
implement the IVI Layer Manager API, which includes clipping of
surfaces.
The names weston_view_set_mask() and weston_view_set_mask_infinite()
mirror the existing weston_layer_set_mask*() functions.
This view clipping complements the weston_layer clipping, because view
clipping is defined in surface local coordinates, while layer
mask/clipping is defined in global coordinates.
View clipping requires explicit support from the renderers. Therefore a
new Weston capability bit is added: WESTON_CAP_VIEW_CLIP_MASK. Shells
(and all users) of this new API are required to check the capability bit
is set before using the API. Otherwise the rendering will not be what
they expect.
View clips are inherited through the transformation inheritance
mechanism. However, there are restrictions. The clip rectangle can be
set only on the root view of a transformation inheritance tree. The
additional transformations in child views must not rotate the coordinate
axes. These restrictions avoid corner cases in clip inheritance, and
keep the renderer implementations as simple as they are right now.
Renderers only need to do an additional intersection with the clip
rectangle which is always aligned to the surface coordinate system.
For more details, see the API documentation in the patch.
