Currently weston_wm_window_send_configurenotify is only called for
fullscreen clients, and it is written to be correct only in that case.
Fix it up to handle other cases properly so we can use it for them in a
later commit. Synthetic Configure Notify events are relative to the
root window, so this means adding our window co-ordinate when
necessary.

It doesn't need to be using desktop-shell; trying to use it is not

noop-renderer needs to actually access the buffer content, to ensure
that the bad-buffer test works. This was previously done using a
volatile variable, but clang rightly pointed out that the variable
access had no effect (since the volatile stack variable was never read
from, and the source is not volatile), so 9b0b5b57dd changed it to be
explicitly marked it as unused to suppress the compiler warning.
Unfortunately suppressing the warning still leaves the compiler free to
optimise out the access.
Replace the variable decorations with actually using the result of the
read, so we can be really sure that it's never going to be optimised
away.

Our positioning of override redirect windows falls apart when an
app is on the fullscreen layer, because we end up putting its
menus and tooltips beneath it. This patch raises the special
override redirect layer to be just below things like on-screen
keyboards (and, unfortunately, above things like panels).
There is no perfect way to deal with this problem, especially
for content like tooltips that don't come with transience hints.
In some cases override redirect menus could be better placed by
using the parenting/transience information provided with them
at map time, and we should probably do that at some point, but
that would still leave us with tooltips below full screen
applications, and the need for this layer change.

Currently the idle_repaint_source is removed when the output is destroyed.
This covers the most common case: When a monitor is unplugged then the
corresponding DRM output is destroyed and not just disabled.
However, outputs can be explicitly disabled by the shell. In this case the
output is not removed and idle_repaint() may be called for a removed
output.
Remove the idle_repaint_source in weston_compositor_remove_output() to fix
this. And reset the variable to ensure that the source can be created
again.
Removing the source in weston_output_release() is now no longer necessary
since it calls weston_compositor_remove_output().

It's not the most code ever, but it does make desktop-shell somewhat
more complicated for questionable (i.e. no) end-user benefit.

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.

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.

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

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.
