weston_output_transform_coordinate() was supposed to convert from device
co-ordinates to global co-ordinates.
Commit 0f67941c broke that by converting from global to device instead,
which just magically works ok for single untransformed outputs (where the
transformation is identity)

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.

Create a new function weston_compositor_read_presentation_clock() to

Reading the presentation clock is never supposed to fail, but if it
does, this will notify about it. I have not seen it fail yet, though.
This prepares for new testing features in the future that might allow

function for clock_gettime().
All presentation clock readers are converted to call this new function

clock id via a thread-safe mechanism. There shouldn't be anything really

Implement a way to do composition clipping with a region32 given in
source image space.
Pixman does not directly support this kind of operation at all. If you
pixman_image_set_clip_region32() on a source image, it will be ignored
unless you also
pixman_image_set_source_clipping(image, 1);
pixman_image_set_has_client_clip(image, 1);
but then it takes the region from source image and still uses it in the
destination coordinate space. For reference:
http://lists.freedesktop.org/archives/pixman/2015-March/003501.html
That is actually the intended behaviour in Pixman.
This patch implements source clipping by taking each rectangle of the
source clip region, wrapping that sub-rect of the source image in a new
pixman_image_t, and compositing it separately. This might be very heavy as
we are painting the whole damage the number of rectangles times, but
practically always the number of rectangles is one.
An alternative solution would be to use mask images of type PIXMAN_a1,
render the source clip region in it, and set the transformation. You'd
probably also want to cache those images. And because we use the mask to
apply view->alpha, you'd have to use PIXMAN_a8 in those cases.

Change the region argument types in repaint_region(), moving the

position deciding if source clipping is needed or if it can be intersected

surf_region or source clip implying that the transformation is only a
translation.
The region_global_to_output() call is also moved into the callers so
that repaint_region() would not modify caller-provided data. Modifying
caller provided data could be surprising.
