X11 applications expect -geometry command line option to work for
setting the initial window position, but currently this does not work.
During map, detect X11 windows that set an explicit position. This works
by heuristics: if window position is not 0,0 then it is explicitly
positioned. Legacy fullscreen windows are also at 0,0 but these are
detected earlier.
Explicitly store the window position at map request time to detect
client-positioned windows, and use it as the suggested initial position.
weston_wm_window::x and y have been overwritten due to reparenting when
we eventually need the initial position.
This patch requires that the new set_toplevel_with_position() hook is
implemented in the shell.
Note that this patch is about positioning xwayland toplevels, not
override-redirect windows which are already handled.

X11 applications expect -geometry command line option to work for
setting the initial window position, but currently this does not work.
Add provision to relay the initial position through libweston-desktop:
- weston_desktop_api gains a new entry set_xwayland_position
- implement set_toplevel_with_position() in xwayland internal interface
Once xwayland plugin starts calling set_toplevel_with_position(),
libweston-desktop can relay that information to a shell if the shell
wants to hear it.
If a shell does not implement the set_xwayland_position hook, the
old behaviour remains: the shell positions xwayland toplevels like any
other.

To reproduce the problem:
- start weston (x11 backend worked, glamor in Xwayland makes no
difference)
- start xterm
- very very slowly move the pointer in the xterm decorations onto or
away from a button
- the moment the decorations are updated, they will appear incomplete,
e.g. completely without buttons and title text
- if you cause just one more pointer motion event, the decorations will
update to completely drawn appearance
Another way to reproduce the problem is to have an xterm and change its
window title. This is easy if you use a shell prompt that updates the
terminal window title. When the title updates, decorations will be
half-drawn until something happens in XWM.
The fix: flush.
Apparently the drawing commands did not get flushed to the X server
until any other X11 action pushed them through.
xcb_flush() is the real fix here. cairo_surface_flush() is added just
for good measure, because documentation indicates it would be better
used, however it was not strictly necessary to fix the problem in my
experiments.

to frame_set_title() from weston_wm_window_read_properties() into

Do not check for window->name == NULL, because frame_set_title() handles
NULL just fine. Also, once window->name becomes set, it cannot become
NULL again unless strndup() fails. The name string can be reset to
the empty string in any case.

The props array contained offsets to struct members. It is convenient
for writing static const arrays as you only store a constant offset and
compute the pointer later. However, the array was not static to begin
with, the atoms are not build time constants. We can as well just store
the pointer directly in the array.
Entries that did not use the offset had bogus offsets, producing
pointers to arbitrary fields. They are changed to have a NULL pointer.
If the code unintentionally used the pointer, it will now explode rather
than corrupt memory.
Also explain the use of the #defined constants and #undef them when they
get out of scope. This clearly documents that they are just a convenient
hack to avoid lots of special cases in the function.

The legacy fullscreen state needs to be detected at MapRequest time,
because that is when the X11 client has alredy set up the initial window
state.
Doing it at xserver_map_shell_surface() meant that it would be done as a
response to Xwayland creating the wl_surface and XWM receiving the
WL_SURFACE_ID ClientMessage, whichever came later. At that point the X11
client might still be setting things up in theory, though in practice
most of the X11 communication has already happened when
xserver_map_shell_surface() gets called.
The real reason for this is to clean up xserver_map_shell_surface() from
everything that would affect drawing the decorations. This patch is one
part of that clean-up.
The weston_output_weak_ref logic is not put into compositor.h, because
there are no other users for it at this time. We need to protect against
the output going away.
A side-effect of this patch is that saved_width and saved_height will
now get overwritten also for legacy fullscreen windows. Previously, they
were left to zero as far as I could tell.
NOTE: This stops override-redirect legacy fullscreen windows from being
detected as fullscreen. MapRequest processing does not happen for OR
windows. These windows get detected as type XWAYLAND instead.

When we create a new view, assign it to the primary plane from the
beginning.
Currently, every view across the compositor will be assigned to a plane
during every repaint cycle of every output: the DRM renderer's
assign_planes hook will either move a view to a drm_plane, or to the
primary plane if a suitable drm_plane could not be found for the output
it is on. There are no other assign_planes implementation, and the
fallback when none is provided, is to assign every view to the primary
plane.
DRM's behaviour is undesirable in multi-output situations, since it
means that views which were on a plane on one output will be demoted to
the primary plane; doing this causes damage, which will cause a spurious
repaint for the output. This spurious repaint will have no effect on the
other output, but it will do the same demotion of views to the primary
plane, which will again provoke a repaint on the other output.
With a simple fix for this behaviour (i.e. not moving views which are
only visible on other outputs), the following behaviour is observed:
- outputs A and B are present
- views A and B are created for those outputs respectively, with SHM
buffers attached; view->plane == NULL for both
- current buffer content for views A and B are uploaded to the
renderer
- output A runs its repaint cycle, and sets keep_buffer to false on
surface B's output, as it can never be promoted to a plane; it does
not move view B to another plane
- output B runs its repaint cycle, and moves view B to the primary
plane
- weston_view_assign_to_plane has work to do (as the plane is changing
from NULL to the primary plane), calls weston_surface_damage and
calls weston_surface_damage
- weston_surface_damage re-uploads buffer content, possibly from
nowhere at all; e508ce6a notes that this behaviour is broken
Assigning views to the primary plane when created makes it possible to
fix the DRM assign_planes implementation: assign_planes will always set
keep_buffer to true if there is any chance the buffer can ever be
promoted to a plane, regardless of view configruation. If the buffer
cannot be promoted to a plane, it must by definition never migrate from
the primary plane. This means that there is no opportunity to hit the
same issue, where the buffer content has already been discarded, but
weston_view_assign_to_plane is not a no-op.
