When picking a size for the last slice in a texture, Cogl would always
pick the biggest power of two size that doesn't create too much
waste and is less than or equal to the previous slice size. However
this can end up creating a texture that is bigger than needed if there
is a smaller power of two.
For example, if the maximum waste is 127 (the current default) and we
try to create a texture that is 257 pixels wide it will decide that
the next power of two (512) is too much waste (255) so it will create
the first slice at 256 pixels wide. Then we only have 1 pixel left to
allocate but Cogl would pick the next smaller size that has a small
enough waste which is 128. But of course 1 is already a power of two
so that's redundantly oversized by 127.
This patch fixes it so that whenever it finds a size that would be big
enough, instead of using exactly that it picks the next power of two
up from the size we need to fill.

A Clone:source property might be NULL, and we should not penalize
performance when we can just bail out early, because that would kind of
defeat the point.
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.
