It's not the most code ever, but it does make desktop-shell somewhat
more complicated for questionable (i.e. no) end-user benefit.
When desktop-shell is back in more healthy shape it could potentially be
reintroduced, but for now it's just making it more difficult to reason
about desktop-shell and fix it.

weston_compositor_reflow_outputs() assumes that all output are positioned from
left to right with no gaps in the same order in which they where created.
If the shell moves an output with weston_output_move() then this assumption is
no longer true. So stop reflowing the outputs in the case. The shell is now
responsible for positioning all outputs as needed.

"The Window Manager MUST set _NET_FRAME_EXTENTS to the extents of the
window's frame", so this is probably something we should be doing.
Some programs (such as some versions of Firefox) expect this to be present,

Instead of closing the window directly by calling close_handler() use a
deferred task to do that instead.
That way we avoid a potential invalid access on a link which was
previously removed, due to the fact both window_destroy() and
touch_handle_up() traverse the same list.
This is an alternative to 841.

By moving the application of view_alpha after pre-multiplication we can
simplify main() considerably.
The cost is that for straight-alpha input or color_pipeline() we might
be doing three multiplications more than before. However,
a) the cost of running color_pipeline() probably dominates anyway, and
b) to get straight-alpha input you have to use a future Wayland
extension that probably won't be advertised without color management.
So we keep the optimization for the simple case (no color management)
while potentially incurring a small cost on the heavy case (with color
management).

According to the wm-spec we must keep the _NET_WM_STATE property updated
to reflect the current state of the window.
This has been biting me when firefox starts maximized, then I click the
maximize button to toggle to unmaximized state. The next time I mouse over
the maximize button (which causes the frame to be re-rendered with the
maximized button in a highlighted state) we re-read the window state and
weston then believes the window is maximized even though it is being
rendered in a not-maximized state.
Update the state when we change maximized status so this doesn't happen.

When we leave fullscreen or maximized mode we restore a saved window
position. This is expected, but that saved position was saved when window
geometry was set to have shadows rendered.
Since we restore a saved position that had shadow geometry, we don't want
to move the window when we set geometry again, or we'll move away from the
intended saved position.
I guess this is a counter-proposal to !614Fixes#454

There is missing dependency on linux-dmabuf-unstable-v1-server-protocol.h
header file in backend-headless, backend-drm and backend-x11. That files
do not depend on that header, in fact. But by this moment they've had
that implicit dependency due to linux-dmabuf.h header.
With specific set of meson configure options the protocol header is not
generated at the right time, what causes build error in 100% cases using
small amount of building threads (from -j1 to -j8).

Move the struct image_header and get_image_prop() into a header where we
can share these useful helpers between more test code. While doing that,
drop the unused field 'depth', rename into image_header_from(), and
introduce a helper to get u32 pointer to the beginning of a row. These
helpers should make pixel iterating code easier to read and safer (less
room for mistakes in address computations, and asserts).
Use the shared 'struct image_header' instead of the local one. The
intention is to make the code easier to read by using the same helpers
everywhere.
Width, height and stride use type 'int' because Pixman API uses that
too.

"max bpc" property is meant for working around faulty sink hardware.
Normally it should be set to the maximum possible value so that the
kernel driver has full freedom to choose the link bpc without being
artificially forced to lower color precision.
The default value is 16 because that is a nice round number and more
than any link technology I've heard is using today which would be 12.
Also offer an API set the value, so that weston.ini could be used in the
next patch for sink workaround purposes.

Commit 62ab6891db intended to change the angle calculation
so that the a time delta since the first frame would be used
instead of the absolute time. That was done in order to ensure
the angle would always start with the same value, allowing users
to differentiate left and right, which again is needed when
testing flipped transforms.
However, the `benchmark_time` variable is unsuitable for that
purpose as it gets reset on each benchmark interval, abruptly
changing the angle.
Thus introduce a dedicated variable.

Move gen_ramp_rgb() down in the file where the TEST() specific code
begins. This way we first have a big block of fixture setup code which
creates an ICC profile, and the next big block is the actual test client
code. gen_ramp_rgb() belongs with the latter.
This makes the file structure slightly more logical.

The new name better matches the contents of the test.
Currently the test creates output ICC profiles with matrix-shaper and
cLUT forms, and tests that basic color conversion from input to output
color space is correct.
The common theme in this test program is to create ICC profiles to be
used as output profiles. In the future this can include more kinds of
testing, e.g. linear blending. OTOH, this test program will always be
limited to SDR because HDR testing probably will not use ICC files.

To support heterogeneous outputs, the output must be created by the
same backend as the head(s) it is created for. Solve this by always
