50849ac1fd cookbook: Use new API to reverse timeline
clutter_timeline_set_reverse() can be used to
automatically reverse a timeline's direction each time
it completes, so use that in looping animation recipe and
examples.

ee9a4d02bb cookbook: Add example of scaling a texture
Added a simple application for scaling a
texture while keeping the mouse pointer over
the same coordinates on its surface.

b47b2f4749 cookbook: Added animated scaling example
Added an example showing scaling of an actor on
each of the scaling gravity settings (NORTH_WEST, NORTH etc.),
with a mark indicating the center being used.

Displays the transformed size and position, updated
on each paint of the actor.

animation itself doesn't.

f1b2f1e8c5 cookbook: Example of animated movement with ClutterState

with other animation (in this case, scaling).

c3cbf1533f cookbook: Example using allocation-changed to sync actor size

a0f63a3153 cookbook: Example of using a bind constraint for an overlay
Example code which loads an image into a texture, and resizes
the image in response to +/- key presses. The overlay is
a transparent rectangle which is bound to the height and
width of the texture; on clicking the texture, the overlay
is made visible by increasing its opacity.

This demonstrates how to use constraints to simplify code
for resizing an actor which is "dependent" on another actor.

82ab00930b cookbook: Simplified and clarified example code

some more comments, to further simplify and support the
recipe.

d7a3e35f46 cookbook: Cleaned up the "animations reuse" example
With some help from pippin, moved variable declarations
into more sensible positions within their functions,
changed a function name, and found a better way

been destroyed.

d4190cbf8c cookbook: Refactored reusable animation example

then create a new script and get the animation each
time a rectangle is clicked.

Removes the need to reparent onto the background and
copy property values to the rectangle after the animation,
and generally much cleaner.

abef73bb58 Replace cogl_color_set_from_* with cogl_color_init_from_*

60ff660d42 cookbook: Added a second example to show "overlapping" transitions

be easily overlapped when using ClutterAnimator (two
sequences of 5 transitions, simultaneous with two
sequences of 1 transition).

this example as well.

connection from ClutterScript by passing -export-dynamic
to linker.

e332236b87 cookbook: Added a longer slideshow example
Cross-fading between two images is straightforward,
but cycling between more than two is more efficient
if done by copying COGL textures between the
two textures, rather than trying to reposition the
textures.

The example demonstrates how to reuse a pair of
textures to cycle through multiple images.

c230fd8dfd cookbook: Made code examples more consistent

the Clutter API code sample.
