The ClutterBrightnessContrastEffect effect class allows changing the
brightness and contrast levels of an actor.

We can use the __COUNTER__ macro or, failing that, the __LINE__ macro to
ensure that we don't declare dummy variables more than once with the
same name.
The comment says that we're going to load textures in a loop until we
still have work to do, or if one iteration took more than 5
milliseconds, to avoid blowing up our frame budget, but the check is for
5 seconds, which is hardly a sensible value.
We remove 2 pixels from the height of the cursor, but we should also
remove the same amount from the position on the y axis, so that the
cursor caret appears centered in the allocated height.

ClutterScript should be able to automatically call gettext() and friends
on strings loaded from a UI definition, prior to passing the string to
the object it is constructing.
The basic implementation is trivial:
- set a translation domain on the ClutterScript instance
- mark the translatable strings inside the JSON data, like:
"property" : {
"translatable" : true,
"string" : "a translatable string"
}
The hard part is now getting the tools we use to extract the
translatable strings to understand the JSON format we use inside
ClutterScript.
Let's keep a budget of 16.6 milliseconds per frame, and reduce it by the
amount of time spent in each phase of the frame processing. If any phase
goes over the allocated budget then we use the diagnostic mode
facilities to warn the app developer.
It is sometimes useful to be able to have better control on when a
repaint function is called. Currently, all repaint functions are called
prior to the stages update phase of the frame processing.
We can introduce flags to represent the point in the frame update
process in which we wish Clutter called the repaint function.
As a bonus, we can also add a flag that causes adding a repaint function
to spin the master clock.
In theory, handlers connected to the ::allocation-changed signal may be
able to modify the actor's real allocation and allocation flags,
especially now that we use STATIC_SCOPE; let's avoid this, so that we
don't regret it later.
This has been converted to a Cogl-based test in the cogl source tree
so there is no need to maintain it here anymore.

The show and hide implementation inside ClutterStage ended up being
recursive, and the hide implementation would actually show the children
of the stage unconditionally.
Whoopsie.
