When the ClutterTextBuffer support inside ClutterText was merged, it
introduced a regression that was identified and fixed in bug 659116.
The optimization to not paint empty ClutterText actors is only valid
is the actor is not editable, or if the cursor is not visible.
Courtesy of GLib and GTK+. The abicheck.sh is a simple, Linux-only,
script to check that we're not leaking private symbols, or that the
clutter.symbols file hasn't been updated.
In theory, it should go inside the distcheck phase.
A bunch of private symbols have escaped into the SO; let's rectify this
situation by using the '_' private prefix, or making them static as they
should have been.
ClutterActor should be emitting signals defined on the ClutterContainer
interface, as well as ensuring that manipulating the scene graph is
still possible from within them.
The new unit checks that we're emitting signals, by implementing
something similar to the Bin class available in toolkits like gtk, st,
and mx — i.e. a container that can only hold one child at any given
point.
Cogl now requires that all applications integrate their main loop with
Cogl so that it can listen for events from winsys. This patch just
adds Cogl's GSource to the main loop.

Some of Cogl's experimental apis have changed so that the buffer apis
now need to be passed a context argument and some drawing apis have been
replaced with cogl_framebuffer_ drawing apis that take explicit
framebuffer and pipeline arguments.
These changes were made as part of Cogl moving towards a more stateless
api that doesn't rely on a global context.
This patch updates Clutter to work with the latest Cogl api and bumps
the required Cogl version to 1.9.5.

Similar to the clutter_actor_iter_remove(), but it'll call destroy()
instead of remove_child().
We can also reimplement the ::destroy default handler using it, and make
it more compact.
There is a typo in the check for a negative index: the index variable
should be index_, not index - unfortunately, the latter can still be
resolved to index(3), so compiler and linker are perfectly happy.

An editable ClutterText will reset the selection and cursor whenever the
contents are changed — even if those contents are the same. As this may
confuse the user, we should check if we're setting the exact same string,
and bail out if necessary.
The reverse of position_to_coords().
While providing documentation on how to implement it using the
PangoLayout API, I realized that the verbosity of it all, plus the usage
of the Pango API, was not worth it, and decided to expose the method we
are using internally.
GValueArray is on its way to deprecation in GLib; as far as the
ListModel class is concerned, a plain C array of GValue is a perfectly
suitable replacement for the GValueArray usage. It actually is an
improvement, given that it's going to take less memory.
ClutterActor stopped requiring to override the map and unmap virtual
functions some time ago.
Now that ClutterActor implements the Container interface, overriding map
and unmap to control the MAPPED state of the children is pretty much
going to be a source of bugs and misunderstandings.
Plus, the ordering of the unmap, destroy, dispose, and finalize calls
should be be documented properly.
The documentation should clarify all that.
• Clear up what's deprecated.
• Remove mentions of set_parent/unparent, and use add_child/remove_child
instead.
• Clarify that reparent may not touch the MAPPED state.
