[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.
