* clutter/clutter-fixed.c:
	(clutter_value_transform_fixed_int),
	(clutter_value_transform_fixed_double),
	(clutter_value_transform_fixed_float),
	(clutter_fixed_get_type): Add GValue transformation functions
	for ClutterFixed; copying a CLUTTER_TYPE_FIXED GValue into
	a G_TYPE_FLOAT/G_TYPE_DOUBLE one will automatically transform
	the fixed point representation into a floating point one. Also
	add the G_TYPE_INT transformation function to do a plain
	fixed->int copy.

	* clutter/clutter-units.c:
	(clutter_value_transform_unit_int),
	(clutter_unit_get_type): Add a unit->int transformation function.
