From our perspective, a bitmask is pretty much the same as an enum, so

Every shells have an implementation of weston_desktop_api structures.
It includes some callbacks to listen to xdg_surface signals. Committed callback
is one of them.
Currently, the xdg_shell don't invoke the weston_desktop_api->committed
callback when the xdg_surface is initial stage or no surface content.
In the case: the client attached a null buffer after the valid buffer,
the shell isn't going to invoke to xdg_surface committed, and don't know
the surface is disappeared. If the surface is fullscreen, we will get
a black background on the screen until a new valid frame come. That
should not happen.

Possibly the least useful place to use this, as the input comes directly
from pixman rects, and the output is more complicated than usual, but
I guess consistency counts for something.
There is some small benefit in switching to weston_matrix_transform_coord
to hide the perspective normalization step and the homogenous coords.

All through weston we have code that passes int x, y or
float x, y or wl_fixed_t x, y pairs. These pairs are frequently
converted to/from wl_fixed_t and other types.
We also have struct vec2d and struct weston_geometry which also
contain coordinate pairs.
Let's create a family of coordinate vector structures for coordinate
pairs and use it anywhere we sensibly can.
This has a few benefits - it helps remove intermediate conversion
between fixed/float/int types. It lets us roll the homogenous
coordinate normalization bits into helper functions instead of
needing them open coded throughout the source.
Possibly most importantly, it also allows us to do some compile time
validation of what coordinate space we're working in.

One variant is used when a view is being positioned relative to a parent,
the other is when the view is being given an absolute position in the
global space.
This will help later when surface and global coordinates are different

In commit d611ab24fd "libweston: Update
view transforms more often", a call to weston_view_update_transform()
was introduced to desktop_surface_committed(). It was added between the
point in which we call unset_fullscreen() and
shell_configure_fullscreen(), right after the view geometry dirty bit is
set.
There's a scenario with dual displays in which this change resulted in
the surface being alternated between two outputs:
---
Dual display configuration:
1st display: DP1, with scale 1 - origin 0, 0
2nd display: DP2, with scale 2 - origin 1920, 0
We start the app with the cursor on DP2. Function
desktop_surface_committed() gets called a few times, and it ends up
setting shsurf->saved_x and shsurf->saved_y to the origin of DP2.
Application wants to become fullscreen on DP1, so when the surface gets
committed again and desktop_surface_committed() gets called, we have the
following sequence:
desktop_surface_committed():
was_fullscreen = shsurf->state.fullscreen
is_fullscreen = weston_desktop_surface_get_fullscreen()
if (!weston_surface_is_mapped(desktop_surf))
map(shell, desktop_surf)
return;
/* POINT A, this is important for understanding the issue. */
if (shsurf size didn't change and
fullscreen state didn't change)
return;
if (was_fullscreen)
/* This function calls weston_view_set_pos(saved_x,
* saved_y), and the saved position is the origin of
* DP2. Then it invalidates the saved position */
unset_fullscreen(shsurf)
if (is_fullscreen && !shsurf->saved_position_valid)
/* Saves the position (as it just have been
* invalidated), which will be the origin of DP2
* again. */
shsurf->saved_x = shsurf->view->geometry.x
shsurf->saved_y = shsurf->view->geometry.y
shsurf->saved_position_valid = true
/* This function calls weston_view_assign_output(), which then
* calls weston_surface_assign_output(). The effect of these two
* functions is that the view gets assigned to an output, and to
* choose the output it takes into consideration the position in
* which it is and the area that it occupies on the output. As
* the view has been moved to the origin of DP2, it gets
* assigned to this output. Then Weston sends the enter/leave
* surface events. */
weston_view_update_transform()
if (is_fullscreen)
/* This function positions the view on DP1, because
* that's the output in which the wine app wants to
* become fullscreen. */
shell_configure_fullscreen(shsurf)
/* Now we call weston_view_update_transform() again to each view
* of the surface, and so we end up sending enter/leave surface
* events. But notice that now we are positioned on DP1. */
wl_list_for_each(view, &surface->views, surface_link)
weston_view_update_transform(view);
The next time the surface gets committed and desktop_surface_committed()
gets called, the same sequence will happen. So we'll continue in this
weird loop.
The reason why the surface size changes and we don't return in POINT A
in this scenario is because the application uses a viewport, and then
when its surface moves to the output with scale 2 it sets the surface
size to half its size. That happens for apps that want to keep a
reasonable DPI on scaled displays.
This only happens after the change that introduced the call to
weston_view_update_transform() in this function. Without this call we'd
not reposition the view on DP2 and send enter/leave events at that
point.
---
So in order to avoid that, be more careful before calling
unset_fullscreen() and then shell_configure_fullscreen(). Only do that
when:
- the surface was not fullscreen, and now it becomes.
- the surface was fullscreen, but now it becomes fullscreen on a
different output.
In order to be consistent, do something similar to the maximized state.

Xwayland pop-up menus aren't displayed until the mouse moves, or some other
action causes the compositor to repaint.
This is because the shell knows nothing about xwayland override redirect
windows, so it won't assign them an output. Without an output, the
surface commit won't cause a repaint.
Fix this with brute force by updating their geometry on commit. If the
geometry is dirty (and it will be for new surfaces), this will cause an
output to be assigned before the upcoming weston_surface_schedule_repaint()

This fixes the situation where screen share seat is not released upon
compositor shut down.
This will have a cascading side-effecting of resulting in an invalid libinput
device reference assert, like the following:
../src/libinput.c:2169: libinput_device_unref: Assertion
`device->refcount > 0' failed.
That happens because at compositor shutdown, the seat created by the
screen share module will *still* be acccesible in compositor instance
seat list, effectively resulting in an invalid unref for a non-existent
libinput device.
This patch rectifies that in such a way that upon compositor shut down
we release the seat in the screen share module which would implicitly
remove it from the compositor instance seat list.
