An error makes the client exit, which cleans up the resources anyway.
Note (Jason Ekstrand):
This is safe for two reasons. First, we should be handling object
destruction nicely anyway. Second, in each of these cases, the resources
don't have any implementation or destruction set so it has absolutely no
effect on the rest of weston whether we destroy it now or later.
If we're fading a view with weston_fade_run() and half way through we
want to unfade it we can use weston_fade_update() to set a new alpha
target. When the animation finishes, reset_alpha() is called which
ensures the alpha value of the view is exactly as requested.
Although weston_fade_update() was updating the spring target so the
animation would look fine, it would then reset to the alpha target
given in the first call to weston_fade_run().
It looks like that in the great conversion introducing weston_view, one
conditional was forgotten from the code that builds the global flat list
of views. Sub-surfaces are added to the view list specially, as they are
not governed by their presence in a layer's view list, and therefore
need an explicit check for mappedness.
The bug, missing the explicit check, caused sub-surfaces to enter the
global view_list regardless of their state. This lead to the pointer
focus picking code processing them, and as the input region defaults to
infinite, picking these unmapped surfaces. Clients then get confused
about the wl_pointer.enter events with unexpected wl_surface.
To trigger this issue, it is enough to just create one additional
wl_surface and make it a sub-surface of a main surface that is or gets
mapped. Literally, just a wl_subsomcpositor_get_subsurface() call is
enough. At some point later, the unmapped sub-surface will get pointer
focus, depending on view stacking order.
Fix the issue by adding a is_mapped check when building the view_list.
Note, that 95ec0f95aa accidentally also
prevents this bug from happening, because it adds a test against the
transform.masked_boundingbox in weston_compositor_pick_view().

If a client does this:
1. create a main window and map it
2. create a wl_surface, and make it a sub-surface of the main window
3. set the sub-surface to desync
4. commit content to the sub-surface to map it
Then step 4 should cause the sub-surface to become mapped. However,
Weston fails to schedule a repaint in that case, so the sub-surface will
not appear until something else causes a repaint on that output, e.g.
the main window.
A quick and dirty fix is to set the output mask for the surface in
Weston, which allows the repaint to be scheduled. This patch implements
that, and might only work right on single-output systems.
A proper fix would involve rewriting the whole "is surface mapped"
mechanism in Weston, to not rely on output assignments but to have a
separate flag for "mapped", and figuring out how to schedule repaints
for the right outputs.

this adds a mechanism to mask the views belonging to a layer
to an arbitrary rect, in the global space. The parts that don't fit
in that rect will be clipped away.
Supported by the gl and pixman renderer only for now.
This introduces a new struct, weston_layer_entry, which is now used
in place of wl_list to keep the link for the layer list in weston_view
and the head of the list in weston_layer.
weston_layer_entry also has a weston_layer*, which points to the layer
the view is in or, in the case the entry it's the head of the list, to
the layer itself.
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.
This new structure is used for both weston_surface.pending and
weston_subsurface.cached.

I've updated this based on comments, simplifying the command handling.
Currently the screen-share module uses a hard-coded command to start the
fullscreen shell server. This patch causes the module to read the command from
the weston config file (from the "command" key in the "screen-share" section).
The default value remains the same (i.e. to run weston with the RDP backend and
fullscreen shell), but is now located in the weston config file.
As well as allowing the arguments to the fullscreen shell server to be changed,
this also permits an alternative fullscreen shell server to be used if required,
without needing to recompile. Since the command is run as the user running
weston, this should not pose any additional security risk.

No functional changes, just adjusting for API changes in libinput:
- libinput_destroy() replaced by libinput_unref()
- log functions now take a libinput context, userdata is gone
- udev seat creation is now libinput_udev_create_context() and
libinput_udev_assign_seat()

Animations are run off the repaint cycle so if there's nothing to
repaint, an animation will stop running. This is usually not a problem
as each frame function of an animation causes something to change and
therefore a repaint to happen. This patch helps detect when the
animation isn't in said case and triggers a repaint to keep the
animation running.
This problem was found by using weston_move_scale_run() to move a view
onscreen from completely off. The very first time the animation frame
function was called the progress wasn't enough to move it into
view. The compositor saw there was nothing to repaint and stopped
doing anything else. When something else (like a pointer move) forced
a redraw, the view's position was very much onscreen and jumped into
view in an ugly way.
Both weston_move_scale_run() and weston_slide_run() were broken in
commit 3a869019. Commit a4a6f161 fixed and explained the problem for
weston_slide_run() but weston_move_scale_run() remained broken.
To fix weston_move_scale_run(), weston_view_animation_run() is also
required. It was removed when _run() was split into two functions
_create() and _run() in commit f5cc2b56, but _run() was not added in
this commit.
This is to avoid recursing into weston_compositor_build_view_list()
and therefore fix crashing when destroying a stack of visible subsurfaces
due to weston_compositor_build_view_list() being called recursively
and corrupting the lists it works on.

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.

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.

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.

send_configure was originally modelled after
wl_shell_surface::send_configure, which takes these arguments. However,
the X WM and xdg_surface::configure variants don't use these arguments.
We already store the resize edges for a surface while it's being
resized, so just use the saved state in the wl_shell_surface variant.
There is no need to unset WAYLAND_DISPLAY and WAYLAND_SOCKET when screen-share
launches the fullscreen shell server. This was done originally in case the
launched server decided to use the wayland backend based on the presence of
these. However, we pass a command line argument telling it to use the RDP
backend, which overrides the automatic backend selection based on the
environment.
Keeping these environment variables allows the launched fullscreen shell server
to know the original server's display name, which it may need in order to show
a configuration UI.

In order to apply the zoom transformation to the output matrix, Weston was
doing the following:
• Create a temporary matrix to hold the translation
• Invert the translation matrix using weston_matrix_invert into
another temporary matrix
• Scale that matrix by the scale factor
• Multiply the current matrix with the temporary matrix
Using weston_matrix_invert to invert a translation matrix is over the top.
Instead we can just negate the values we pass to weston_matrix_translate.
Matrix multiplication is associative so creating a temporary matrix to hold the
scale and translation transform should be equivalent to just applying them
directly to the output matrix.
Make sure that we don't map a device to an invalid output pointer and
intead remap devices when an output is created.
v2: fix the error with libinput too.
