The list of surfaces used by weston_compositor_pick_surface() is
maintained in list of surfaces stored on the compositor. This list is
generated from the surfaces across all the layers using
weston_compositor_build_surface_list.
When destroying a surface the surface is "unmapped" with
weston_surface_unmap which removes it from the layer list. However since
the compositor surface list was only being rebuilt when the output was
repainted a call to weston_compositor_pick_surface before the next
output repaint would use an outdated surface list containing surfaces
that have been partially destroyed.

The panel and background were never created for hotplugged outputs and
since some parts of the code assume that they always exist that would
lead to desktop-shell client to crash in that case.
This was easier to spot when the display was locked, because Weston
respawns the shell client and the user might not notice since there is
no flicker.

This lets the code for adding panel launchers and setting up the
background to be moved into panel_* and background_* functions.
Note that this changes the behavior of the default launcher. Before
this change a default launcher would be added only if there was no
config file. Now a launcher is also added if there is no valid
launcher section.
We can get a destroy notify for the frame window after we've removed it
from the hash table. This turns into a NULL pointer deref when we look up
the window and try to use it for debugging printout.
Fixes the failing xwayland test case.
Calling weston_pointer_start_grab can lead to a code path (in this case
when the shell surface is unresponsive) that can try and remove the
popup grab to setup a shell grab.
Ending the popup grab requires removing the surface from the grab's
surfaces list - however the grab had not yet been fully setup so the
grabbed surface was not yet in this list.
With this change we ensure we add the surface to the list before setting
up the pointer grab.

Make sure the center point of a rotation is not rounded to an
integer. It makes the calculation consistent with others in the
shell. It also ensures surfaces rotated 180 degrees are at the
exact same place.
This commit sets the version numbers for all added/created objects. The
wl_compositor.create_surface implementation was altered to create a surface
with the same version as the underlying wl_compositor. Since no other
"child interfaces" have version greater than 1, they were all hard-coded to
version 1.

Originally window.c was requesting version 1 but several clients were
calling version 2 and 3 events including the desktop shell itself.

Window contents cannot be assumed to be fully opaque for windows drawn with
a RGBA visual. The optimization of setting a full opaque region is limited to
windows with a color depth != 32.
In embedded environments, devices that appear as evdev "keyboards" often
have no resemblence to PC-style keyboards. It is not uncommon for such
environments to have no concept of modifier keys and no need for XKB key
mapping; in these cases libxkbcommon initialization becomes unnecessary
startup overhead. On some SOC platforms, xkb keymap compilation can
account for as much as 1/3 - 1/2 of the total compositor startup time.
This patch introduces a 'use_xkbcommon' flag in the core compositor
structure that indicates whether the compositor is running in "raw
keyboard" mode. In raw keyboard mode, the compositor bypasses all
libxkbcommon initialization and processing. 'key' events containing the
integer keycode will continue to be delivered via the wl_keyboard
interface, but no 'keymap' event will be sent to clients. No modifier
handling or keysym mapping is performed in this mode.
Note that upstream sample apps (e.g., weston-terminal or the
desktop-shell client) will not recognize raw keycodes and will not react
to keypresses when the compositor is operating in raw keyboard mode.
This is expected behavior; key events are still being sent to the
client, the client (and/or its toolkit) just isn't written to handle
keypresses without doing xkb keysym mapping. Applications written
specifically for such embedded environments would be handling keypresses
via the raw keycode delivered as part of the 'key' event rather than
using xkb keysym mapping.
Whether to use xkbcommon is a global option that applies to all
compositor keyboard devices on the system; it is an all-or-nothing flag.
This patch simply adds conditional checks on whether xkbcommon is to be
used or not.

v2 by Rob Bradford <rob@linux.intel.com>: the original version of the
patch used a "raw_keycodes" flag instead of the "use_xkbcommon" used in
this patch.

In preparation for upcoming changes, we want to make sure that apps
written with the toy toolkit continue to operate properly if no XKB
keymap is received. If there's no XKB keymap, then we shouldn't
try to figure out keyboard modifier states (since we probably don't
even have equivalents of PC-style modifiers).

This change tweaks weston_pointer_clamp to take into consideration if a
seat is constrained to a particular output by only considering the
pointer position valid if it is within the output we a constrained to.
This function is also used for the initial warping of the pointer when a
constraint is first established.
The other two changes are the application of the constraint when either
a new device added or a new output created and therefore outputs and
input devices can be brought up in either order.
v2: the code in create_output_for_connector has been spun off into a
new function setup_output_seat_constraint (Ander). The inappropriate
warping behaviour has been resolved by using weston_pointer_clamp
(Pekka).
This refactors the code out from clip_pointer_motion into a function of
its own which can then be used elsewhere to clamp the pointer
coordinates to the range of the outputs.
This change also makes the caller of clip_pointer_motion use this new
function.
This change spills the code for looking up a seat by name and then
potentially creating it if it doesn't exist into a new function called
udev_seat_get_named.
This change allows us to reuse this code when looking up the seat
when parsing seat constraints per output.
The fix to not call glTexImage2D() on every attach does not properly
set the texture damage region appropriately when the surface has a
buffer transform with 90 or 270 degrees rotation, since it would simply
multiply the buffer dimensions by the buffer scale, but in this case
width and height are inverted.
A possible fix for this would be to add the properly transformed region
to the texture damage region. However, there is a conversion back to
buffer coordinates when doing the actual upload and the entire buffer
needs to be uploaded anyway. So we just set a flag signalling that and
handle that special case in gl_renderer_flush_damage().
Checking for gs->num_images for determining the previous buffer type
when attaching is not reliable. The number of images is never cleared
in the SHM path, so after a switch from an EGL buffer to SHM, every
following attach of an SHM buffer will happen with gs->num_images > 0,
and the code will assume the previous buffer was an EGL one.
Fix this by adding a buffer_type field to gl_surface_state.
We were assigning drag from the resource user data, which was wrong
(resource data is the weston_seat) and confusing since drag is later
assigned newly malloc()ed memory.
We used to refcount the data source, but switched to using a destroy signal
instead. When we switched we forgot to free the source insted of
unreffing it.
With the change to move free()ing of the wl_resource into wayland-server, we now have
a few cases where we double free the resource in the destructor. This patch
removes those.
This commit adds a weston_buffer structure to replace wl_buffer. This way
we can hold onto buffers by just their resource. In order to do this, the
every renderer.attach function has to fill in the weston_buffer.width and
weston_buffer.height fields.
