The asynchronous loading code could do with some modernization.
First of all, we should drop the internal GMutex held when manipulating
the boolean flags: it's far too expensive for its role, and modern GLib
provides us with bitlocks that are quite a lot faster.
Then we should consolidate most of the implementation into something
smaller and more manageable.
The ClutterGeometry type is a poor substitute of cairo_rectangle_int_t,
with unsigned integers for width and height to complicate matters.
Let's remove the internal usage of ClutterGeometry and switch to the
rectangle type from Cairo.

When testing the performance of an application, it's often useful to
force it to continuously redraw instead of going idle to help measure
the frame rate. This just adds a CLUTTER_PAINT=continuous-redraw which
causes the master clock to queue a redraw on all of the stages
just before it prepares its source.

When the viewport gets expanded because the actor extends off the edge
of the screen, instead of applying the transformation to the root of
the modelview transformation it is now applied to the end of the
projection transformation. This should end up with the same
transformation. This fixes a problem when the offscreen effects are
nested and the inner effect would try to pick up the current modelview
transformation to rescale it to fit the new viewport size. In this
case the modelview would have already been scaled for the size of the
outer viewport so it would end up wrong.

Cogl has a similar script which has had the following additional
changes:
* Don't pass -c to wget
* Explicitly download and run config.guess
This patch just syncs up with those.
https://bugzilla.gnome.org/show_bug.cgi?id=659625
* Updated dependencies, glib 2.28 and cogl 1.8.0
* Mesa has removed mesa_wgl.h from its headers
* added -I$ROOT_DIR/include to the CFLAGS to include the headers from
our prefix (say <GL/gl.h>) before the system ones

A ClutterText in password mode should have the ability to show the last
input character. This feature allows easier password entry on platforms
with unreliable keyboards, such as touchscreens or small devices.

Add a setting that controls whether ClutterText actors in password mode
should display the last input character for a defined time. This helps
on touch-based interfaces.

In _clutter_actor_set_default_paint_volume we were returning FALSE if an
actor has an empty allocation because we were claiming it doesn't have a
paint-volume. Actually an empty/degenerate pv is valid and has different
semantics to returning FALSE because FALSE means the pv is unknown and
so Clutter will have to assume the worst - that the pv is basically
un-bounded.

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.
