Pixman uses y-x banded rectangles to represent regions. We use these
y-x banded rectangles to generate triangle fans, resulting in more
geometry than strictly necessary to draw the screen.
This patch combines the bands to reduce geometry for complex scenes.

If the client is small (< 128 pixels in any ward),
then the shadows overlap and create dark lines behind clients.
This is a problem mosly with pop-up menues. The lines become observable
when the menu has less than three items. The other case is when
the client doesn't restrict its size when resizing (try
'weston-eventdemo --max-width=1 --max-height=1' for example)

weston key bindings are supposed to eat the key events, and not pass it
on to clients, and indeed the wl_keyboard.key event is not sent. But
we must also not put the key in the keys array to pass to client with
the wl_keyboard.enter event, or else we may send the 'eaten' one too.
In the case of a key binding hiding a surface having the keyboard focus,
the shell may decide to give the focus to another surface, but that will
happen before the key is released, so the new focus surface will receive
the code of the bound key in the wl_keyboard.enter array.

Committing to an xdg_surface with a NULL buffer is currently illegal in
the mutter implementation, so this simply causes the client to error and
exit.
It seems the reason the client did this was so it could add its own
frame callback, but toytoolkit actually provides accurate everything we
need. Just use its functions instead to get the time and schedule a
redraw.

With the more accurate definition of wl_surface roles in Wayland,
enforce the restriction: a role is always set permanently, and
attempting to change it is a protocol error.
This patch is based on Jasper's patch:
http://lists.freedesktop.org/archives/wayland-devel/2014-August/016811.html
The difference in this patch compared to his are:
- send role errors on the interface whose request triggers it, not on
wl_surface
- an interface could have several requests assigning different roles,
cannot use wl_interface as the unique key; use an arbitary string
instead
- ensure in window-manager.c that create_shell_surface() ->
create_common_surface() is never called with surface->configure set,
to avoid compositor abort
- use wl_resource_post_no_memory() where appropriate instead of
hand-rolling it with wl_resource_post_error()
Ideally we would not add weston_surface::role_name field, but use
weston_surface::configure. At the moment this is not possible though,
because at least shell.c uses several different roles with the same
configure function. Drag'n'drop uses two configure functions for the
same role. The configure hook is also reset in several places,
which is not good for role tracking.
This patch overlooks the wl_surface roles assigned in privileged
extensions: screensaver, panel, background, lock, input panel.

This started as a copy of simple-shm.c before it was converted to
xdg_shell.
This demo excercises the presentation feedback interface in five
different modes:
- A continuous repaint loop triggered by frame callbacks, and using
immediate commits, just gathering presentation feedback and computing
some time intervals for statistics.
- The same as above, except with 1s sleep before actually repainting as
a response to frame callback. This tests how well the compositor can
do a repaint from idle state (not continuously repainting), assuming
nothing else is causing repaints.
- A continuous repaint loop triggered by 'presented' events rather than
by frame callbacks. If Weston uses an appropriate scheduling
algorithm, this mode achieves the smallest possible frame latency
(below one output refresh period).
In all modes, all frames are pre-rendered at startup, so no rendering
happens during the animation.

The DRM backend already queried the DRM about the clock id, just let the
DRM backend set the presentation clock from that.
For all other backends which do not get a timestamp from the driver,
call the software clock setter to choose a suitable clock.
Report the chosen clock via presentation.clock_id event to clients.
In finish_frame(), upgrade the argument from uint32_t milliseconds to
struct timespec which can accurately hold the presentation clock values.
This will be needed when weston_output_finish_frame() starts to send out
presentation_feedback.presented events.
While at it, replace gettimeofday() calls with clock_gettime() using the
chosen presentation clock, so we manufacture presentation timestamps
from the presentation clock when the gfx drivers cannot give us a proper
timestamp.

Add accurate presentation timing features to Wayland: queueing and
feedback.
This specification is based on the draft written by Frederic Plourde
<frederic.plourde@collabora.co.uk> and redesigned by Pekka Paalanen.
The RFC v2 version is from
http://lists.freedesktop.org/archives/wayland-devel/2014-January/012988.html
Changes in v3:
* associate presentation time to current surface contents
This implements the suggestion from
http://lists.freedesktop.org/archives/wayland-devel/2014-February/013066.html
which prevents surface content from jumping backwards in time if a
client retroactively queues an update with a target time in the past.
* use 64-bit tv_sec in presentation
The time_t type used in struct timespec could be almost anything. POSIX
probably defines it to be an integer, but not the size. Apparently it is
usually 'long', which makes it 64-bit on x86_64.
To be able to fully represent timespec values returned by clock_gettime,
change the protocol to use 64 bits for the tv_sec part.
* define an error for invalid tv_nsec
This allow us to rely on the normalized timestamp form.
* define some interactions with sub-surfaces
Sub-surface cached state updates (synchronized mode) are designed
especially for resizing. As queued updates are not meant to produce any
resizing-like effects, they also do not trigger any sub-surface
operations.
* add sub-headings as xml comments
* queued update cannot map
Because before mapping, the surface has no main output assigned. An
immediate commit is needed anyway, to be able to set all the surface
state, which a queued update cannot touch.
* frame callbacks are not queued
It is not known when queueing frame callbacks would be useful.
Changes in v4:
* remove mentions of the queuing feature
The specification has been split and the queuing feature will be added
back in another version of the extension.
* add flags argument to 'presented' event
Describe the nature of how the update was presented to screen and the
characteristics of the feedback information. No flags have been
defined for now.
* add a protocol error code for invalid flags
Changes in v5:
* remove the destroy method for the feedback object
The protocol object should instead be automatically destroyed after
a 'presented' or 'discarded' event has been triggered.
* some grammatical corrections to the specification

Additionally, weston_output_mode_switch() should be called when
output->original_mode is non-NULL (which indicates we had a temporary
mode set). The comparison to current_mode results in a lot of
