Clutter advertises itself on X11 as implementing the _NET_WM_PING protocol,
which is needed to be able to detect frozen applications; this allows us to
stop the destruction of the stage by blocking the CLUTTER_DELETE event and
wait for user feedback without the Window Manager thinking that the app has
gone unresponsive.
In order to implement the _NET_WM_PING protocol properly, though, we need
to add the _NET_WM_PID property on the Stage window, since the EWMH states:
[_NET_WM_PID] MAY be used by the Window Manager to kill windows which
do not respond to the _NET_WM_PING protocol.
Meaning that an unresponsive Clutter application might not be killable by
the window manager.

* Do _not_ use CLUTTER_MAJORMINOR to define the installation path
for the headers; we must use CLUTTER_API_VERSION for that.
* Do not put the C compiler flags in the INCLUDES directive.
Bases on a patch by: Gary Ching-Pang Lin <glin@novell.com>
The version number in the title made sense when we were breaking
API with every minor release. Now that we're API stable we can
drop that and make the output in Devhelp and on the website slightly
more good looking.
It is possible to unset the size of an actor specified with set_width()
and set_height() by using:
clutter_actor_set_size (actor, -1, -1);
Which works by unsetting the :min-*-set and the :natural-*-set properties.
Calling set_width(-1) and set_height(-1) separately, though, doesn't work
thus implicitly breaking the assumption that set_size() is nothing more
than set_width()+set_height(). This was obviously due to the face that
pre-1.0 set_width() and set_height() took an unsigned integer as an
argument.
ClutterActor parses positional and dimensional properties with a
custom deserializer. We need to:
- handle G_TYPE_INT64, the default integer type for JSON-GLib
- use G_TYPE_FLOAT for properties, since Actor switched to it
for the pixel-based ones
This makes ClutterScript work again.
The json-types.h header is found by the mere fact of it being
in the project; if we are compiling against the system JSON-GLib
this could be horribly out of date.
We need to use clutter-json.h, which will include the right
header for us.
JSON-GLib moved to a single include scheme, so we should only include
json-glib.h. If we use the internal copy it doesn't matter, since the
header does the right thing.
The clutter-script-parser.c does not have a copyright and license
notices; even though the LGPL is a per-project license and not a
per-file license, having those notices in every source file is a
good idea.
The OS X backend Makefile.am was missing a line concatenation, and
so the -xobjective-c directive was always ignored.
Instead of dumping everything into INCLUDES and LDADD we should follow
what the rest of the backends do, and use per-target CFLAGS and LDADD,
and reserve the INCLUDES to -D and -I directives.

Don't install inside the clutter-MAJOR_MINOR/ directory, but use
the API_VERSION (1.0).
Otherwise we'd have the Clutter headers for 1.x inside:
$includedir/clutter-1.0/clutter
And the JSON-related headers inside:
$includedir/clutter-1.<minor>/clutter
The fix for bug 1750 inside commit b190448e made Clutter-GTK spew
BadWindow errors. The reason for that is that we call XDestroyWindow()
without checking if the old Window is None; this happens if we call
clutter_x11_set_stage_foreign() on a new ClutterStage before it has
been realized.
Since Clutter-GTK does not need to realize the Stage it is going to
embed anymore (the only reason for that was to obtain a proper Visual
but now there's ClutterBackendX11 API for that), the set_stage_foreign()
call is effectively setting the StageX11 Window for the first time.
When we replace the stage Window using a foreign one we also need to
destroy the Window we created, if needed, to avoid leaking resources
all around.

The "catch all" warning for a the mapped invariant violation is too
generic: it doesn't tell you why the invariant was broken in case
we are trying to map an unparented actor - e.g. through a Clone.
in tests/interactive/Makefile.am add wrapper.sh to EXTRA_DIST otherwise
interactive unit tests wont be runnable when building from distributed
tarballs.
The right gcc define is __GNUC__ not __GNUC_. This typo had the side
effect that we were using the non gcc specific debug macros leading to
a less optmised CLUTTER_NOTE () than one could have dreamed of.
The vertex that should be used by the apply_relative_transform
is the one passed in as const, and the result should be placed
inside the non-const ClutterVertext. Currently, we are using
the latter, and thus the function is completely useless.
The README has been updated to say that you can use the script under
MSYS and also to contain a pointer to OAH. It also contains the
updated contents of a blog post¹ about building with MSYS.
