This implicitly intersects any clip for redrawing with the stage window
bounds. Without this we were sometimes trying to set huge off screen
scissors leading to undefined clipping results.

Out-of-band transforms are considered to be all actor transforms done
directly with the Cogl API instead of via ClutterActor::apply_transform.
By running with CLUTTER_DEBUG=oob-transform then Clutter will explicitly
try to detect when un-expected transforms have been applied to the
modelview matrix stack.
Out-of-band transforms can lead to awkward bugs in Clutter applications
because Clutter itself doesn't know about them and this can disrupt
Clutter's input handling and calculations of actor paint-volumes
which can lead to visual artifacts.

For god-knows-what reason, at-spi is trying various formats
of strings when registering listeners, triggering an ugly
(gnome-shell:4411): Clutter-WARNING **: invalid object type create
warning in .xsession-errors. Stop doing that.
Also don't leak temporary string arrays that are a side-effect
of passing parameters around as formatted strings.

A bunch of private functions we use when parsing got exposed accidentaly
to the list of public symbols by virtue of not having the leading '_'
that we use to filter them out of the shared object — all the while the
header that declares them is a private, non installed one.
Let's rectify this situation with a bit of minor surgery on the code.
The priv->text field cannot ever be NULL, so we don't need to check for
that in a series of places. We also need to assert() that pre-condition
in the couple of places where we set the contents of the ClutterText
actor, namely in set_text_internal() and set_markup_internal().
