Some animated cursor sets use very long delays, but until now we'd use the
frame callback and update the cursor at the display framerate anyway.
Now we use a timerfd to drive cursor animation if the delay is longer
than 100ms, or the old method for short delays.

It is redundant to check x*alloc's return value for null pointers, since
they are guaranteed to either return non-NULL or terminate the program.
In cases where we memset the malloc'd memory to 0, we can more
efficiently use the xzalloc() routine. zalloc looks for opportunities
to return memory chunks that have already been zero'd out, so it can
provide better performance.
This patch addresses this warning, reported by Denis Denisov:
[clients/window.c:1164] -> [clients/window.c:1166]: (warning) Possible
null pointer dereference: surface - otherwise it is redundant to check
it against null.
[clients/window.c:4513] -> [clients/window.c:4514]: (warning) Possible
null pointer dereference: surface - otherwise it is redundant to check
it against null.

We have the Weston command line option '--no-config' which is meant to
prevent loading weston.ini at all. It works for Weston itself, but it
does not work for any clients that also want to read weston.ini.
To fix that, introduce a new environment variable WESTON_CONFIG_FILE.
Weston will set it to the absolute path of the config file it loads.
Clients will load the config file pointed to by WESTON_CONFIG_FILE. If
the environment variable is set but empty, no config file will be
loaded. If the variable is unset, things fall back to the default
"weston.ini".
Note, that Weston will only set WESTON_CONFIG_FILE, it never reads it.
The ability to specify a custom config file to load will be another patch.
All programs that loaded "weston.ini" are modified to honour
WESTON_CONFIG_FILE.

Certain circumstances may lead to the "force" clause in
input_set_pointer_image() being reached when the current cursor
is blank or unset. These are special cursors that don't have
images, and they need to be handled differently than image cursors.
This patch puts the special cursor handling in its own function and calls
it from both places that need it. Previously only the frame callback
handler did this correctly.

wl_display_dispatch() just dispatches events that are in

then it will wait for them. But only dispatching
the events doesn't guarantee that we got all the global announcements,

When a toytoolkit client redraws, the toolkit syncs the parent and
geometry. If a client redraws often (such as the terminal drawing a huge
amount of output), this can spam the compositor with requests and may
result in the client's eventual being killed.
We don't need to send requests for changing the geometry or parent if
these haven't changed. So remember the last geometry and parent, and
update them only if needed.

The experimental versioning has not been updated when it was supposed
to. Let's try to be better at it now, as xdg-shell is close to have its
first stable version.
Bump the version now to bring the world into the same exact version.
There may be some protocol changes still coming, but we try to land them
before 1.6 gets out. Those changes will bump the experimental version
again as needed.
When 1.6.0 is released, the experimental version will no longer be
bumped, and no incompatible protocol changes will be made. Xdg-shell.xml
file will move to Wayland in 1.7.0, drop the experimental versioning,
and become stable.

Currently, there is a fun flicker when toggling maximization or
fullscreen on a window in mutter or more sophisicated compositors
and WMs.
What happens is that the client want so go maximized, so we
calculate the size that we want the window to resize to (640x480),
and then add on its margins to find the buffer size (+10 = 660x500),
and then send out a configure event for that size. The client
renders to that size, realizes that it's maximized, and then
says "oh hey, my margins are actually 0 now!", and so the compositor
has to send out another configure event.
In order to fix this, make the the configure request correspond to
the window geometry we'd like the window to be at. At the same time,
replace set_margin with set_window_geometry, where we specify a rect
rather than a border around the window.
Once we've updated the window state and scheduled a resize, we know that
the next frame we send to the compositor will match the configured state.
This means we can just ack the configure immediately and not jump
through hoops to try to do it from the redraw stage.
As the protocol says, the states determine how the width and height
arguments should be interpreted, so it makes logical sense to do the
interpretation after.
Add a new state_changed_handler callback to the window to know when the
window has changed state; the terminal will use this to know when the
window started and ended its resize operation, and modify the terminal's
titlebar accordingly.
Currently, there's a race condition. When resizing from the left, and
a client attaches a buffer after the resize ends, you suddenly see the
buffer jump to the right, because the resize ended while multiple
attaches were in-flight. Making resize a state can fix this, as the
server can now know exactly when the resize ended, and whether a commit
was before or after that place.
We don't implement the correct tracking in this commit; that's left as
an exercise to the reader.
Additionally, clients like terminals might want to display resize popups
to display the number of cells when in a resize. They can use the hint
here to figure out whether they are resizing.
The states system, so far, has been a complicated mix of weird APIs
that solved a real race condition, but have been particularly ugly
for both compositors and clients to implement.
It's a confusing name that comes from the ICCCM. The ICCCM is best
forgotten about.
With the addition of the potential new "transient" role meaning a
parent-relative toplevel like a long-lived popup, used for e.g.
tooltips, the set_transient_for name will become even more confusing.
Toytoolkit was not designed to handle input from subsurfaces and
instead it expects subsurfaces to have an empty input region. That way
input events for subsurfaces are generated on the main surface and
there is no need to convert coordinates before reporting the event to
the user.
However it is possible that a subsurface has a non-empty input region,
but in that case those events aren't properly processed. The function
window_find_widget() assumes the coordinates are in the main surface
coordinate space, and ends up chosing the wrong widget.
This patch changes the input code to completely ignore input events from
subsurfaces. This option was chosen instead of ensuring that the input
region on those surfaces is always empty since there's no enforcement
that a subsurface should completely overlap with the main surface. If
an event happens in the area of the surface that doesn't overlap, the
event could cause a completely unrelated surface to be picked.
https://bugs.freedesktop.org/show_bug.cgi?id=78207
Ideally, we'll update the key event handling to deliver events to widgets,
but in the meantime, just blocking key event delivery while a grab is
active goes a long way.
