Create a new function weston_compositor_read_presentation_clock() to
wrap the clock_gettime() call for the Presentation clock.
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
controlling the presentation clock. Right now it is just a convenience
function for clock_gettime().
All presentation clock readers are converted to call this new function
except rpi-backend's rpi_flippipe_update_complete(), because it gets its
clock id via a thread-safe mechanism. There shouldn't be anything really
thread-unsafe in weston_compositor_read_presentation_clock() at the
moment, but might be in the future, and weston core is not expected to
need to be thread-safe.
This is based on the original patch by

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
final_region computation to the caller. The caller is in a better
position deciding if source clipping is needed or if it can be intersected
into the final_region via a simple translation. This avoids
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

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.
