Use wl_list_for_each_safe instead, which is designed to

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.
With most of the code in send_configure_for_surface, the helper
methods don't give us that much benefit, so stop using them. We
can't kill them off, as they're part of the shell interface and
used by the WM.
Currently, there's a giant bug in how xdg-shell state management
is done. If a client calls set_fullscreen and then set_maximized,
it will get two configure events:
=> set_fullscreen
<= configure(800, 600, [STATE_FULLSCREEN])
=> set_maximized
<= configure(800, 560, [STATE_FULLSCREEN, STATE_MAXIMIZED])
Since fullscreen takes precedence over maximized, the client will
render full-screen at 800x600 first, and then 800x560 next. As
a result, the surface gets the wrong size.
This is because the code that sends out configure requests is
"immediate" -- when an app calls set_maximized, we immediately
send out the configure event that would have happened if we
transitioned immediately into maximized mode.
In wl_shell, this is correct behavior. However, in xdg-shell,
this is wrong. State needs to be more carefully managed in
xdg-shell, as states aren't exclusive.
Pull all the code that sends out configure events out and send
them centrally, based on Weston's on surface state management.
This should work with both wl_shell and xdg_shell's strategies.
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.
xdg-shell mandates that the FULLSCREEN state means that we must match
the size that we were configured to, at least by default. Other states
or protocol extensions might relax this requirement, but at least for
now implement the behavior specified in the protocol documentation.
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.

Before in the recursive automake setting, we had tests/logs/ for
explicitly created test log files. There is a Makefile rule to
remove the logs directory on 'make clean'. The rule broke on moving to
non-recursive make, since now we have logs/, not tests/logs/.

If the test is named xwayland.weston, then the automake test harness
keys it off xwayland.log. Making xwayland.log runs the test.
The test harness has implicit rules to create a %.log from all of
%$TEST_EXTENSIONS. So we have implicit rules to create %.log from %.la
and %.log from %.weston.
We also build xwayland.so, which produces xwayland.la.
When the test harness goes running the xwayland test, it ends up using
the %.la rule, which is wrong. It passes xwayland.la as the test name to
weston-tests-env, which then loads it as a plugin into Weston and waits
for Weston to exit. Which it never does.
Fix this by making the test have a different name than the Xwayland
plugin.

The error handling for the function that writes the encoded frame on
the disk was bogus, always assuming the buffer supplied to the encoder
was too small. That would cause a bigger buffer to be allocated and
another attempt to encode the frame was done. In the case of a failure
to write to disk (due to ENOSPC, for instance) that would cause an
endless loop.

If simple-touch ran on a compositor with multiple seats, and the first

The zoom translation is just a scale and a translate. The translation
is calculated based on the coordinates of the pointer which are in
global space. Previously the calculated translation was transformed by
the output transformation so that when the zoom transform is applied
after the output transform then it will be correct. However if we just
apply the zoom transformation first then we get the same result
without the zoom code having to be aware of the output transformation.
This also fixes weston_output_transform_coordinate which was applying
the output and zoom transforms in the wrong order.

With xdg_shell wl_shell starting to diverge in how they work, there's
less shared code in set_fullscreen(). The problem is that the xwayland

the fullscreen transition. Add shell_interface_set_fullscreen() for
the shell interface set_fullscreen hook to use.

If the scale for the cursor surface doesn't match that of the output
then we shouldn't use the cursor overlay because otherwise it will be
drawn at the wrong size. This problem is particularly noticable with
multiple pointers because it randomly alternates between drawing one
cursor or the other at a larger size depending on which one gets put
in the cursor overlay.
When converting output-relative coordinates (such as from an input
event) to global coordinates it now takes into account the zoom
transform. Previously this would only work for the primary pointer
because the transform doesn't affect the primary pointer position due
to that way zoom follows the mouse. Touch events and multiple pointers
were not working correctly.
