The DragAction should, by default, drag the actor to which it has been
applied, instead of delegating what to do to the developer. If custom
code need to override it, g_signal_stop_emission_by_name() can be called
to stop the default handler to ever running.

The ClutterActor API should have modifier methods for adding, removing
and retrieving Actions and Constraints using the ClutterActorMeta:name
property - mostly, for convenience.
To demonstrate that constraints can be used to reposition actors in a
resizable stage, set the :user-resizable property to TRUE, and spend the
next 15 minutes playing with the stage size.
AlignConstraint is a simple constraint that keeps an actor's position
aligned to the width or height of another actor, multiplied by an
alignment factor.
DragAction is an Action sub-class that provides dragging capabilities to
any actor. DragAction has:
• drag-begin, drag-motion and drag-end signals, relaying the event
information like coordinates, button and modifiers to user code;
• drag-threshold property, for delaying the drag start by a given
amount of pixels;
• drag-handle property, to allow using other actors as the drag
handle.
• drag-axis property, to allow constraining the dragging to a specific
axis.
An interactive test demonstrating the various features is also provided.
This updates test-cogl-offscreen to give an example of setting up a
CoglFramebuffer with a Clutter style 2D coordinate system with (0,0) top
left and (framebuffer_width, framebuffer_height) bottom right.
test-cogl-tex-polygon creates a separate material so that it can set
the texture filters. However in the paint functions that use
cogl_polygon it was calling cogl_set_source_texture which replaces the
material and ends up always using GL_LINEAR. This patch makes the
paint functions assume the correct source is set up instead of trying
to select a new source.
Added new "homogeneous" mode to ClutterBoxLayout, that makes layout children
get all the same size.
This is heavily inspired in the "homogeneous" attribute available in GtkBox,
but simplified as we don't have padding nor borders in box layout, only
spacing.
Also added to test-box-layout a key to set/unset homogeneous mode.
* Coding style fixes.
* Added proper test for homogeneous mode in box layout.
* Fix in homogeneous mode.

The FlowLayout fails to provide a preferred size in case no sizing is
specified on one axis. It should, instead, have the preferred size of
the sum of its children, depending on the orientation property.

It was passing the number of vertices to
cogl_vertex_buffer_draw_elements but instead it should take the
maximum index which would be the number of vertices minus one. This
was causing errors to be reported with the checks filterset of Bugle.
If an actor is lying on the border of the Stage it might miss the LEAVE
event when the pointer of a device leaves the Stage window. Since the
backend is unsetting the Stage back pointer on the InputDevice we can
queue the emission of a LEAVE event on the pointer actor as well.

ClutterAnimator is a class for managing the animation of multiple
properties of multiple actors over time with keyframing of values.
The Animator class is meant to be used to effectively describe
animations using the ClutterScript definition format, and to construct
complex implicit animations from the ground up.

A small doubt has risen about the use of CoglTextureUnit in materials:
will texture matrices still work if we have several materials, each of
them having at texture on the same texture unit? The answer is yes!
test-cogl-multitexture has been extended to use 2 materials with about
the same setup except a little difference: the texture matrices for the
lightmaps rotate in opposite directions.
While at it, changed the rotation behaviour by an implicit animation
with a small additional bonus bling.
The extension keyboard support in XInput 1.x is hopelessly broken.
Nevertheless, it's possible to use some bits of it, as we prefer the
core keyboard events to the XInput events, thus at least having proper
handling for X11 key events on the Stage window.
• The enter/leave event line should take into account the case where
the related field is set to NULL (meaning entering from off-stage
and leaving the stage).
• The ButtonRelease line shows the click count but uses the button; the
button *and* the click count should be displayed for both ButtonPress
and ButtonRelease, to verify they match.
The output of test-events is a bit of a mess; this patch should clean
it up a little bit - at least enough for it to be useful again during
visual inspection.
The test-text "fake scrolling" code stopped working somewhere between
0.8 and 0.9, with the new layout code. Instead of the ::cursor-event
signal it should use an approach similar to the Scrollable interface in
the Moblin User Experience toolkit.
Right now, it makes sense to ignore this code entirely.

ClutterLayoutManager does not have any state associated with it, and
defers all the state to its sub-classes.
The BoxLayout is thus in charge of controlling:
• whether or not animations should be used
• the duration of the animation
• the easing mode of the animation
By adding three new properties:
• ClutterBoxLayout:use-animations
• ClutterBoxLayout:easing-duration
• ClutterBoxLayout:easing-mode
And their relative accessors pairs we can make BoxLayout decide whether
or not, and with which parameters, call the begin_animation() method of
ClutterLayoutManager.
The test-box-layout has been modified to reflect this new functionality,
by checking the key-press event for the 'a' key symbol to toggle the use
of animations.
