Robert Bragg 65e7bc6363 Replaces uses of CoglAngle with floats (Though the CoglAngle type remains)
The CoglAngle type can still be used for focused optimisations since the type
and macros remain. Uses of CoglAngle within Cogl have been replaced with floats;
COGL_ANGLE_FROM_DEG is no longer used anywhere and the replacements for
cogl_angle_cos -> cosf (same for sin) have been fixed to convert float values
in degrees to radians. This fixes the cogl-primitives API.

# The ClutterFixed type and macros now use floats, but we are keeping the
# CoglFixed type + macros using fixed point so now we convert all uses of
# the Cogl fixed point macros within Clutter proper to use the ClutterFixed
# macros instead.
