9130dc1311 util: optimize _clutter_util_fully_transform_vertices
Instead of unconditionally combining the modelview and projection
matrices and then iterating each of the vertices to call
cogl_matrix_transform_point for each one in turn we now only combine the
matrices if there are more than 4 vertices (with less than 4 vertices
its less work to transform them separately) and we use the new
cogl_vertex_{transform,project}_points APIs which can hopefully
vectorize the transformations.

Finally the perspective divide and viewport scale is done in a separate
loop at the end and we don't do the spurious perspective divide and
viewport scale for the z component.

013b2433f0 viewport: consistently use floats for viewports
OpenGL < 4.0 only supports integer based viewports and internally we
have a mixture of code using floats and integers for viewports. This
patch switches all viewports throughout clutter and cogl to be
represented using floats considering that in the future we may want to
take advantage of floating point viewports with modern hardware/drivers.

3040b140bc paint_volume: Splits out clutter_paint_volume code
This splits out all the clutter_paint_volume code from clutter-actor.c
into clutter-paint-volume.c. Since clutter-actor.c and
clutter-paint-volume.c both needed the functionality of
_fully_transform_vertices, this function has now been moved to
clutter-utils.c as _clutter_util_fully_transform_vertices.

8be43b5285 Add P_() macro for translating property strings
The P_() macro adds a context for the property nick and blurb. In order
to make xgettext recognize it, we need to drop glib-gettexize inside the
autogen.sh script and ship a modified Makefile.in.in with Clutter.

79acb088e7 Remove mentions of the FSF address
Since using addresses that might change is something that finally
the FSF acknowledge as a plausible scenario (after changing address
twice), the license blurb in the source files should use the URI
for getting the license in case the library did not come with it.

Not that URIs cannot possibly change, but at least it's easier to
set up a redirection at the same place.

As a side note: this commit closes the oldes bug in Clutter's bug
report tool.

e55966d675 Deprecate clutter_util_next_p2()
The next_p2() function should have never been publicly exposed by
Clutter.

* clutter/clutter-alpha.h:
	* clutter/clutter-alpha.c: Add a data parameter to
	the ClutterAlphaFunc; add a data+destroy parameter
	to clutter_alpha_set_func() and to clutter_alpha_new(),
	and turned the latter into clutter_alpha_new_full();
	add a simple, empty constructor clutter_alpha_new().

	These changes makes writing bindings a tad more easy,
	as bindings require passing their own functions in
	order to call the real alpha function.

	* clutter/clutter-behaviour.h: Clean up the header.

	* clutter/clutter-behaviours.[ch]:
	* clutter/clutter-behaviour-opacity.[ch]:
	* clutter/clutter-behaviour-path.[ch]:
	* clutter/clutter-behaviour-scale.[ch]: Split the
	ClutterBehaviourPath, ClutterBehaviourOpacity and
	ClutterBehaviourScale into their own files as they
	have been growing a bit. Fix ClutterBehaviourPath
	API.

	* clutter/clutter-media.h: Remove the commented
	"metadata_available" signal: gtk-doc chokes up on that.

	* clutter/clutter-timeline.h:
	* clutter/clutter-timeline.c: Remove the useless
	ClutterTimelineAlphaFunc signature; add missing accessor
	methods for the properties; clean up a bit.

	* clutter/clutter-util.h:
	* clutter/clutter-util.c: Remove unneeded function
	clutter_util_can_create_texture().

	* clutter/clutter-feature.h: Sync the name of
	clutter_feature_get_all() with the name declared
	in clutter-feature.h.

	* clutter/Makefile.am:
	* clutter/clutter.h: Update.

	* examples/behave.c: Update to the new ClutterAlpha
	constructor.

	* examples/super-oh.c: Use the right pointer and avoid
	the compiler making a fuss about it.
