A lockup was reported by fargoilas on #clutter and removing the server grab in
clutter_x11_texture_pixmap_sync_window fixed the problem.
We were doing an x server grab to guarantee that if the XGetWindowAttributes
request reported that our redirected window was viewable then we would also
be able to get a valid pixmap name. (the composite protocol says it's an
error to request a name for a window if it's not viewable) Without the grab
there would be a race condition.
Instead we now handle error conditions gracefully.
If the stage is unrealized (such as will be the case if the stage was
created with clutter_stage_new) then it would set the size of the
stage display but it was not setting the fullscreen_on_map flag so it
never got the _NET_WM_STATE_FULLSCREEN property. Now it always sets
the flag regardless of whether the window is created yet.
There was also problems with dual-headed displays because in that case
DisplayWidth/Height will return the size of the combined display but
Metacity (and presumably other WMs) will sensibly try fit the window
to only one of the monitors. However we were setting the size hints so
that the minimum size is that of the combined display. Metacity tries
to honour this by setting the minimum size but then it no longer
positions the window at the top left of the screen.
The patch makes it avoid setting the minimum size when the stage is
fullscreen by checking the fullscreen_on_map flag. This also means we
can remove the static was_resizable flag which would presumably have
caused problems for multi-stage.
The call to "cmp" to compare a built file with its current version
should use the -s (silent) command line switch. This avoids a ugly
message on the console when building Clutter the first time.
The clutter_get_current_event_time() function will return the event
timestamp coming from a Clutter event. Clutter might synthesize or
throttle events, so the function cannot be used when dealing with
backend-specific use cases.
The X11 backend is the only backend supported by Clutter that makes
use of timestamps, so it's altogether fitting that it should come
with a specific function to deal with the timestamps of the X events.
Bug 1178 - No enter / leave events on actors when pointer leaves the
stage window
The patch is mostly thanks to Johan Bilien with small modifications
based on suggestions by Owen Taylor.
The X11 backend now listens for enter and leave notifications. Leave
notifications get translated directly to a CLUTTER_LEAVE
event. Clutter can detect these special events because the source
actor is NULL in which case it sets the source actor to the last known
actor and then sets the last known actor to NULL.
Enter notifications just get translated to CLUTTER_MOTION events which
will cause Clutter to generate an enter event through the usual code
path.
clutter-x11.h declares clutter_x11_set_display twice, which means code using
clutter doesn't compile cleanly with -Wredundant-decls.

When processing a motion event, we need to spin the event loop two extra
times to ensure that any enter/leave events that might have been synthesized
are pumped through (otherwise they end up being pushed down the queue and
never processed).
While X11 Pixmap and Window types only have 32-bits of data, they
are actually 'unsigned long'. Change the "window" and "pixmap"
property of ClutterX11TexturePixmaps to be ulong.
This fixes 64-bit bugs where ClutterGLXTexturePixmap passed a
reference to Pixmap to g_object_get("pixmap", &pixmap, ...);

Since Clutter changed to using a layout scheme the handling_configure
flag no longer works because the allocate method is not invoked
immediately during the call to set_size from the ConfigureNotify
handler. However it is also no longer neccessary because the resizes
are effectively batched up until a relayout is run so it won't cause
an infinite loop of resize and notify events anyway.
Continuation of the fix in commit 00a3c69868.
Instead of using a separate flag for the resize process, just
delay the setting of the CLUTTER_ACTOR_SYNC_MATRICES flag on the
stage to the point when we receive a ConfigureNotify event from
X11.
This commit will break the stage embedding into other toolkits.
There is a race condition when we resize a stage before showing
it on X11.
The race goes like this:
- clutter_init() creates the default stage and realize it, which
will cause a 640x480 Window to be created
- call set_size(800, 600) on the stage will cause the Window to be
resized to 800x600
- call show() on the stage for the first time will cause COGL
to set up an 800 by 600 GL viewport
- the Window will be mapped, which will cause X to notify the
window manager that the Window should be resized to 800x600
- the window manager will approve the resize
- X resizes the drawable to 800x600
To fix the race, we need to defer COGL from setting up the viewport
until we receive a ConfigureNotify event and the X server has resized
the Drawable.
In order to defer the call to cogl_setup_viewport() we add a new
private flag, CLUTTER_STAGE_IN_RESIZE; the flag is checked whenever
we need to change the viewport size along with the SYNC_MATRICES
private flag. Thus, cogl_setup_viewport() will be called only if
SYNC_MATRICES is set and IN_RESIZE is not set.
Clutter has a set of command line options that are added to every
application by means of clutter_init() or by obtaining the Clutter
GOptionGroup and using g_option_context_parse(). Thus, every Clutter
application will automatically have an --help command line switch
showing the list of options and their description.
At the moment, Clutter does not enable localization of the help,
thus making it less than useful on non-English locales.
This patch enables the machinery to create a localization file and
load it when initializing Clutter, by means of the GLib macros and
locale.h API we already use.

Instead of returning CLUTTER_X11_FILTER_CONTINUE always from
clutter_x11_handle_event() return CLUTTER_X11_FILTER_REMOVE if
the event was on a stage and translated to a ClutterEvent.
