For a surface that is already fullscreen making it maximized means to
exit fullscreen then set to it maximized. Instead of doing it, refuse to
do anything until the user explicitly performs that operation.
With this approach we follow other DE (desktop environments) which would
not perform any operation until the user exits fullscreen state.

Exposay was done as a showcase for what we could do with Weston and an
efficient compositing pipeline. This was mostly with the old
vendor-specific Raspberry Pi backend which could actually process that
many surfaces bypassing the GPU.
Given enough bitrot, Exposay is now pretty exemplary as what _not_ to do
in a Weston shell - particularly the way it manipulates existing
weston_views rather than create its own non-destructive stack.
As it's annoying technical debt, a terrible example to others, and not a
very compelling showcase in 2022, just delete it.

This is a minor re-work of how we de-activate and activate the surfaces
in desktop-shell. As activate() is being used for handling keyboard
input events, this basically rectifies that such that activation
happens only if the passed surface is different from the currently
focused surface.

shell-utils contains a number of helpers which are currently in use by
both desktop-shell and kiosk-shell. In order to extend this use to
fullscreen-shell as well (which can benefit from reusing the
weston_curtain infrastructure to be able to create solid-colour views
which may or may not be opaque, as well as one function within
fullscreen-shell which was copied wholesale to shell-utils), we need to
create a separate Meson dependency object, and avoid the existing
pattern of including the source from shared/ within the source list for
each shell.
This requires creating a new top-level directory for these shared helper
functions which are required by each shell, but are not part of
libweston in and of itself.
shell-utils depends on libweston-desktop; libweston-desktop depends on
libweston; libweston depends on shared.
Thus it is not possible to expose a dependency object from the shared/
directory which declares a dependency on the libweston-desktop
dependency, as Meson processes directories in order and resolves
variable references as they are parsed.
In order to break this deadlock, this commit creates a new top-level
directory called 'shell-utils' containing only this file, which can be
parsed by Meson after libweston-desktop (making the libweston-desktop
Meson dependency variable available to the build file to declare a
dependency on that), but before the shells (making the new Meson
depenendency object available to each shell which wishes to use it).
This commit contains no functional changes to any observable code.

Use the common infrastructure we have, rather than open-coding again.
In changing to the common weston_curtain infrastructure which was
introduced in a previous commit, there are two small functional
derivations.
After adding the view to a layer, we explicitly call
weston_view_geometry_dirty(). This is believed to have no functional
impact, as weston_views have their geometry-dirty flag set when they are
created.
weston_surface_damage() is also called to ensure that the surface is
scheduled for a repaint. As there is currently no good common mechanic
in the common code to ensure that output repaint will occur, due to the
damage propagating outwards from the weston_surface, we are forced to
call this to predictably ensure that the output will be repainted after
we have made this change to the scene graph which should result in the
user observing the new content being repainted.
It is possible that these changes are not strictly required in order for
the correct behaviour to occur. However, it is felt that explicitly
adding these calls is perhaps the least fragile way to ensure that the
behaviour continues to be correct and breakage is not observed,
especially with both view mapping and surface damage identified as areas
for future work which could be beneficial to Weston. If it is felt that
these calls can be removed, then this is certainly possible at a later
stage.
Lastly, there are many users within desktop-shell of the common pattern
of creating a weston_curtain and inserting it into the scene graph to be
painted. These users have been an area of both theoretical concern and
real-life observed fragility and breakage recently. By making each user
follow a common and predictable pattern of usage, each user is no longer
its own special case. This should make it easier to make the
desktop-shell codebase more robust, not only simplifying the codebase,
but improving observed behaviour.
In doing this, it is hoped that future structural and interface changes
become easier to make, allowing us to improve some of the more difficult
corners of the libweston API.

Just as we do for fullscreen backgrounds, reuse the curtain infrastructure
for focus animations.
This introduces a small functional change, in that the surface's output
is no longer directly assigned. Instead, we call
weston_view_set_output() ourselves. As setting the weston_view's
position (done from the common helper function of weston_curtain_create
which has been introduced in previous commits) will call
weston_view_set_position(), the view's geometry will be dirtied as a
result.
When the geometry of a weston_view is dirty, it is marked to be updated,
which will occur whilst traversing the view list during output repaint.
This occurs for every view which is currently assigned to a layer; when
building the view list, any view reachable through the view list whose
geometry is dirty will have its position recalculated and an output
assigned. Doing so results in the surface's current output being
updated.
It is believed that there is no functional impact from the
weston_surface not having a primary output assigned between creation and
output repaint being called.

Rationalise it a little bit so we don't need pre-declarations of static
functions, and the order of creation more closely matches the others,
including making the same calls to explicitly set the output.
Doing this makes the behaviour match the other users of the same code
pattern. In making them the same, we make desktop-shell code a little
less magically divergent where people might wonder what the correct
pattern is to use. After we have moved all users to a uniform pattern,
later commits are then able to migrate these users to common helper
code, which reduces code duplication, improves code clarity as it is no
longer necessary to wonder about the exact semantics of every
special-case user of this common pattern, and makes it easier to make
interface changes which improve and clarify the patterns which are
prevalent throughout the desktop-shell code.

Follow-up from commit 'desktop-shell: don't run fade animation if

instead of using weston_surface_destroy().
Signed-off-by: Marius Vlad <marius.vlad@collabora.com>
When a window is closed, Weston will, by default, run a fade out animation and
defer destroying the underlying surface until it completes. However, if the
compositor is sleeping, and therefore not rendering any frames, this animation
will *never* complete. Therefore, if windows are repeatedly created and
destroyed while in sleep mode, these surfaces will keep accumulating, and since
the buffers attached to them may be backed by an fd, eventually the ulimit will
be reached resulting in a potential crash or other errors.
This can be demonstrated repeatedly launching and killing an X11 application
with Xwayland running.
while true; do xterm & pid=$!; sleep 0.5; kill $pid; done
As soon as the compositor goes to sleep, one can observe a steadily growing
list of dmabufs in the output of lsof.
As a fix, desktop_surface_removed should check whether the compositor is active
before kicking off the fade animation. If it is not, it should instead drop the
extra reference taken in desktop_surface_committed and then destroy the surface
immediately.

is dangerous. If you have too many open applications or a small
window, the surface size computed will be negative, crashing
the exposay: "error: weston_view transformation not invertible".
Also, it creates a lot of unnecessary space, making the exposay
unusable when we have a small window or many applications open.
Make inner border to be 10% of surface size and surface size to
be 90% of its original size, avoiding the crashes and making it
more visually pleasant.

Commit "desktop-shell: make get_output_work_area() global" allowed
the usage of get_output_work_area() in exposay. This is necessary to
avoid overlapping the panel when rendering exposay's surfaces.
Use get_output_work_area() to not take into account the panel size,
instead of considering that the whole screen is available to
render exposay's surfaces.

get_output_work_area() can be used by exposay to know the free space
where it can render its surfaces, what avoids overlapping the panel.
Currently this function is declared as static in
desktop-shell/shell.c, so it cannot be used by exposay.
Remove static from get_output_work_area() and add it to shell.h
so it can be used by exposay as well.

In exposay_layout(), int pad is being calculated within the
loop. This is unnecessary, as its value is constant. Move it
out of the loop.
