9229fb6114 [docs] Bring down the undocumented symbols to 2%
The usual pre-release documentation blitzing. Most of the remaining
symbols are either COGL or X11 specific, or dummy interface typedefs.

d1f3190f5b [units] Add more conversion functions
A GValue containing a ClutterUnit should be transformable into a
GValue holding an integer, a floating point value or a fixed point
value.

This means adding more transformation functions when registering
the ClutterUnit GType.

ee883f30d4 Add units-from-em conversion
An em is a unit of measurement in typography, equal to the point
size of the current font.

It should be possible to convert a value expressed in em to
ClutterUnits by using the current font and the current DPI as
stored by the default backend.

93a0454c09 Remove the single-stage units converters
The stage-with/height-percentage converters had been broken by
the multiple-stages support of Clutter 0.8. They are also made
useless by the fact that Units are now floating point values.

The millimeters and typographic points converters also depended
on the default stage, but they can be reworked to use the default
DPI coming from the default Backend instead.

c29a3b4dee [Automatic fixed-to-float.sh change] Hand coded changes for clutter-{fixed,units}
To avoid clashing with all the scripted changes, clutter-fixed.h and
clutter-units.h were manually converted to internally use floats instead of
16.16 fixed numbers.

Note: again no API changes were made in Clutter.

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.

e9ee7f049d Fix last improper usage of ClutterUnits
ClutterUnits should not be used interchangeably as, or with
ClutterFixed values. ClutterUnits should also not be assumed
to be integers.

This commit fixes the last few improper usages of ClutterUnit
values, and adds a CLUTTER_UNITS_FORMAT macro for safely printing
ClutterUnit values with printf().

Bug 1209 - Move fixed point API in COGL

	* 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-primitives.c:
	* clutter/cogl/common/cogl-primitives.h: Update internal usage of

	renderer glyphs cache.

* clutter/Makefile.am: Add clutter-units.c

	* clutter/clutter-units.[ch]: Add a ClutterUnit fundamental

* clutter/clutter-actor.c (parse_units),
	(clutter_actor_parse_custom_node),
	(clutter_scriptable_iface_init): Override the parsing code
	for the x, y, width and height properties of ClutterActor,
	to allow strings with modifiers when defining the position
	and/or the dimensions of an actor. Bare integers are assumed
	as pixels; floating point values in the [0, 1] interval are
	assumed as percentages; strings can have these modifiers:

	  - px - pixels
	  - mm - millimeters
	  - pt - points (at the current resolution)
	  - %  - percentage of the stage

	* clutter/clutter-units.h: Fix the conversion macros

	* tests/test-script.json: Test the new values.
