9a5fab0228 xwm: debug when weston_surface gets created
This comes via Wayland, WL_SURFACE_ID comes via X11. They race. Nice to
get both printed.

ed56883970 xwm: split out weston_wm_window_set_pending_state_OR()
Having it in a separate function makes it more clear what it is, and
allows it to be called from elsewhere.

This really is the set_pending_state() alternative for override-redirect
windows, because OR windows do not get a frame window created. Also OR
windows will never hit the normal set_pending_state() because
weston_wm_window_schedule_repaint() special-cased windows without a
frame window and returned early without scheduling.

aabf43d03d xwm: split weston_wm_window_draw_decoration()
Split the function into two:
- weston_wm_window_draw_decoration() that only draws the decorations
with Cairo, and
- weston_wm_window_set_pending_state() which sets up the surface state
to be latches into use on the next commit from Xwayland.

The new weston_wm_window_do_repaint() is the equivalent of the old
weston_wm_window_draw_decorations(), everything still happens the same
way as it was. Just some debug messages have been reworded.

weston_wm_window_read_properties() is moved into
weston_wm_window_do_repaint() because it is not strictly a part of
drawing decorations. The same with resetting repaint_source.

draw_decorations does not need the child position nor xwayland
interface. Also some convenience variables have been eliminated.

set_pending_state code has been un-indented by one level, so the change
is best viewed with whitespace changes ignored.

This patch makes the code more readable, and prepares for calling the
draw_decorations and set_pending_state from different places.

77a6d95a0f shell: implement set_xwayland_position
Store the initial xwayland position explicitly in struct shell_surface.
New variables are needed, because e.g. saved_x, saved_y are the view
position, and to compute that we need the window geometry, which is not
available before the first commit, so it's not available at
set_xwayland_position() time.

Regression: kcachegrind (Qt 4, X11), the first menu invocation will
slightly misplace the menu if the window has not been manually moved.

Problem: geometry is not taken into account due to a race between XWM
drawing decorations and Xwayland committing the first buffer.

Use the same debugging guard as XWM.

v3: merged with "desktop-shell: debug set_position_from_xwayland"

882aff0932 xwayland: detect initially positioned X11 windows
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.

37111e157a libweston-desktop: add set_xwayland_position API
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.

db7b9f3438 xwm: fix intermittent half-drawn decorations problem
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.

c9ca2c0262 xwm: move set_title and set_pid
Move the calls to set_title() and set_pid() out of
weston_wm_window_read_properties() and into the three callers, each
slightly different.

xserver_map_shell_surface(): already calls these functions after
creating the shell surface, so no need to add calls.

weston_wm_handle_map_request(): can be called only on unmapped (in X11)
Windows, so no need to add calls.

weston_wm_window_draw_decoration(): window->shsurf and window->surface
are either both set or both NULL, so the check for window->shsurf is
removed when moving the set_title() and set_pid() calls under a
window->surface check.

9a330e1abb xwm: move frame_set_title() into draw_decoration()
The only thing using the frame title is frame_repaint(). Move the call
to frame_set_title() from weston_wm_window_read_properties() into
weston_wm_window_draw_decoration() where the only call to
frame_repaint() is.

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.

This change is prompted by future refactoring where at
weston_wm_window_read_properties() time the frame might not have been
created yet.

20111d5d53 xwm: clarify props[] in weston_wm_window_read_properties()
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.

505237e9f8 xwm: detect legacy fullscreen on MapRequest
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.
