Whenever the allocation is changed on a child of a ClutterTableLayout
and animations are not in effect then it would store a copy of the
allocation in the child meta data. However it was not freeing the old
copy of the allocation so it would end up with a small leak.
Instead of just changing it to free the old value this patch makes it
store the allocation inline in the meta data struct because it seems
that the size of an actor box is already quite small compared to the
size of the meta data struct so it is probably not worth having a
separate allocation for it. To detect the case when there has not yet
been an allocation a separate boolean is used instead of storing NULL.

All the nifty things you discover when translating strings not exposed
to anyone. First the clutter-wide record of the number of typos in one
string. Second, ClutterTexture happened to have the only property blurbs
ending with a '.', remove them.
the "position" property of ClutterText is really the position of the
cursor. Rename the nick accordingly not to confuse it with the position
of the actor itself and be consistent with all the other cursor-related
properties.
The descriptions for the 'y-align' and 'x-align' properties talk about a
layer and a layer manager. It seems that these properties are the
alignement factors relative to the BinLayout, so document them
accordingly.
There are ordering issues in the pixmap destruction with current and
past X11 server, Mesa and dri2. Under some circumstances, an X pixmap
might be destroyed with the GLX pixmap still referencing it, and thus
the X server will decide to destroy the GLX pixmap as well; then, when
Cogl tries to destroy the GLX pixmap, it gets BadDrawable errors.
Clutter 1.2 used to trap + sync all calls to glXDestroyPixmap(), but
then we assumed that the ordering issue had been solved. So, we're back
to square 1.
I left a Big Fat Comment™ right above the glXDestroyPixmap() call
referencing the bug and the reasoning behind the trap, so that we don't
go and remove it in the future without checking that the issue has been
in fact solved.

After commit 8dd8fbdb some errors appear if you try work directly
against cally:
* cally.pc.in removed some elements. After install clutter, doing
pkg-config --cflags cally-1.0
fails due missing winsys
* cally headers were moved from clutter-1.0/cally to
clutter-1.0/clutter/cally. Applications using it (yes I know,
nobody is officially using it) would require to:
* Change their include.
* Add directly a dependency to cally, in order to use the cally.pc
file with the correct directory include.
Note: Take into account that accessibility support still works (ie:
clutter_get_accessibility_enabled). This bug only prevents
applications to work directly against cally (ie: create a CallyActor
subclass)

Landing the paint-box branch accidentally added two slots to the
ClutterEffectClass vtable, plus the get_paint_volume() function
pointer. This is an ABI break from 1.4.
Like we do for the Quartz backend, we should turn on the -xobjective-c
compiler flag for the Fruity backend.
This does not mean that the backend actually works.
Clutter has long since moved all the RFE and roadmap tracking to
Bugzilla. The TODO is just a relic of an ancient past, where men
were real men, women were real women, and fuzzy little creatures
from Alpha Centauri were fuzzy little creatures from Alpha Centauri.
Don't generate both bz2 and gz tarballs: we only use the former anyway,
and the latter just adds time for distcheck to complete.
The gz tarball will be generated by the remote installation scripts when
publishing the release.
The marshaller was defined as OBJECT,OBJECT,PARAM but the signal
definition used only two arguments. Since the signal never worked
and we never got any report about it, nobody could be possibly
using the ::child-notify signal.
Since we added child properties to the Container interface we made a
guarantee that the ::child-notify signal would be emitted whenever a
property was set using clutter_container_child_set*().
We were lying.
The child_notify virtual function was not implemented, and the signal
was never emitted.
We also used a G_LIKELY() macro while checking for non-NULL on a
function pointer that was by default set to NULL, thus making the
setting of child properties far less efficient than needed.

The clutter stage has a list of entries of actors waiting to be redrawn.
Each entry has a "clip" ClutterPaintVolume member which represents which
how much of the actor needs to get redrawn. It's possible for there to
be no clip associated with the entry. In this case, the clip member is
invalid, the has_clip member should be set to false.
This commit fixes a bug where the has_clip member was not being
initially, explicitly set to false for new entries, and not being
explicitly set to false in the event the clip associated with the entry
is freed.

In all the changes made recently to how we handle redraws and adding
support for paint-volumes we stopped looking at explicit clip regions
passed to _clutter_actor_queue_redraw_with_clip.
In _clutter_actor_finish_queue_redraw we had started always trying to
clip the redraw to the paint-volume of the actor, but forgot to consider
that the user may have already determined the clip region for us!
Now we first check if the given clip != NUll and if so we don't need to
calculate the paint-volume of the actor.
http://bugzilla.clutter-project.org/show_bug.cgi?id=2349
As a convenient test that clipped redraws are working correctly in
response to X pixmap damage this updates test-pixmap to have a repeating
1 second timeout that draws arcs on the pixmap.
One of the later changes made on the paint volume branch before merging
with master was to make paint volumes opt in only since we couldn't make
any safe assumptions about how custom actors may constrain their
painting. We added very conservative implementations for the existing
Clutter actors - including for ClutterTexture which
ClutterX11TexturePixmap is a sub-class of - but we were conservative to
the extent of explicitly checking the GType of the actor so we would
avoid making any assumptions about sub-classes. The upshot was that we
neglected to implement the get_paint_volume vfunc for
ClutterX11TexturePixmap.
This patch provides an implementation that simply reports the actor's
allocation as its paint volume. Also unlike for other core actors it
doesn't explicitly check the GType so we are assuming that all existing
sub-classes of ClutterX11TexturePixmap constrain their drawing to the
actor's transformed allocation. If anyone does want to draw outside the
allocation in future sub-classes, then they should also provide an
updated get_paint_volume implementation.

When using the debug function _cogl_debug_dump_materials_dot_file to
write a dot file representing the sparse graph of material state we now
only show a link between materials and layers when the material directly
owns that layer reference (i.e. just those referenced in
material->layer_differences) This makes it possible to see when
ancestors of a material are being deferred too for layer state.
For example when looking at the graph if you see that a material has an
n_layers of 3 but there is only a link to 2 layers, then you know you
need to look at it's ancestors to find the last layer.
Recipe covers adding handlers for button-press-event and
button-release-event signals on actors, and how to
examine the content of a ClutterButtonEvent via API functions.
The discussion section explains about click count
(the criteria for how clicks get counted, including
distance and time settings); how button numbers are reported;
and how to use ClutterClickAction as an alternative
for press + release in certain scenarios.
