d5e5d35316 Convert the rotation centers to be AnchorCoords
Currently only the Z axis rotation center can be set using a gravity
but the other rotations also store their center as an AnchorCoord for
consistency. Specifying the center as a gravity makes less sense for
the other axes because the actors have no size along the Z axis.

The rotation angles are now stored as gdoubles and the fixed point *x
entry points have been removed.

The Z rotation can now be set with a gravity center using the
following new function:

void clutter_actor_set_z_rotation_from_gravity (ClutterActor   *self,
                                                gdouble         angle,
                                                ClutterGravity  gravity);

7d7372af43 [animation] Move the alpha value to floating point
The current Alpha value is an unsigned integer that can be used
implicitly as a fixed point value. This makes writing an alpha
function overshooting below and above the current range basically
impossible without complicating an already complex code, and
creating weird corner cases.

For this reason, the Alpha value should be defined as a floating
point normalized value, spanning a range between 0.0 and 1.0; in
order to allow overshooting, the valid range is extended one unit
below and one unit above, thus making it -1.0 .. 2.0.

This commit updates the various users of the ClutterAlpha API
and the tests cases.

This commit also removes all the current alpha functions exposed
in the public API.

e82f656590 [Automatic fixed-to-float.sh change] Applies all scripted changes
This is the result of running a number of sed and perl scripts over the code to
do 90% of the work in converting from 16.16 fixed to single precision floating
point.

Note: A pristine cogl-fixed.c has been maintained as a standalone utility API
      so that applications may still take advantage of fixed point if they
      desire for certain optimisations where lower precision may be acceptable.

Note: no API changes were made in Clutter, only in Cogl.

Overview of changes:
- Within clutter/* all usage of the COGL_FIXED_ macros have been changed to use
the CLUTTER_FIXED_ macros.

- Within cogl/* all usage of the COGL_FIXED_ macros have been completly stripped
and expanded into code that works with single precision floats instead.

- Uses of cogl_fixed_* have been replaced with single precision math.h
alternatives.

- Uses of COGL_ANGLE_* and cogl_angle_* have been replaced so we use a float for
angles and math.h replacements.

c9cdf1ef0a Fix an empty block
Remove a stray ';' that prevented the get_bounds() method of the
ClutterBehaviourRotate to correctly return the start angle value.

	* clutter/cogl/common/Makefile.am:
	* clutter/cogl/common/cogl-fixed.c: Add fixed point API, modelled
	after the ClutterFixed. The CoglFixed API supercedes the ClutterFixed
	one and avoids the dependency of COGL on Clutter's own API.

	* clutter/cogl/common/cogl-clip-stack.c:
	* clutter/cogl/common/cogl-primitives.c:
	* clutter/cogl/common/cogl-primitives.h: Update internal usage of
	ClutterFixed to CoglFixed.

	renderer glyphs cache.

	* clutter/clutter-fixed.c:
	* clutter/clutter-fixed.h: ClutterFixed and related API becomes
	a simple transition API for bindings and public Clutter API.

990d0e90a5 * clutter/clutter-actor.[ch]: (clutter_actor_set_rotationx),
(clutter_actor_set_rotation): swapped axis and angle around,
the new argument order is: (axis, angle, x, y, z). Also removed
deprecated rotation functions from header.
Updated use of clutter_actor_set_rotation? in the following files:
* clutter/clutter-behaviour-rotate.c: 
* clutter/clutter-effect.c: 
* tests/test-actors.c: 
* tests/test-project.c:

d0514f4de2 Fix clutter_behaviour_rotate_get_center()
Apply a patch from Neil Roberts (bug 468) that makes the get_center() method
of ClutterBehaviourRotate return the correct tuple of coordinates.

Also, fix some coding style issues and make sure to freeze and thaw the
GObject notification queue when emitting the notify signal on multiple
properties in one method.
