The fog and perspective API is currently split in two parts: - the floating point version, using values - the fixed point version, using structures The relative properties are using the structure types, since they are meant to set multiple values at the same time. Instead of using bare values, the whole API should be coalesced into two simple calls using structures to match the GObject properties. Thus: clutter_stage_set_fog (ClutterStage*, const ClutterFog*) clutter_stage_get_fog (ClutterStage*, ClutterFog*) clutter_stage_set_perspective (ClutterStage*, const ClutterPerspective*) clutter_stage_get_perspective (ClutterStage*, ClutterPerspective*) Which supercedes the fixed point and floating point variants. More importantly, both ClutterFog and ClutterPerspective should using floating point values, since that's what get passed to COGL anyway. ClutterFog should also drop the "density" member, since ClutterStage only allows linear fog; non-linear fog distribution can be achieved using a signal handler and calling cogl_set_fog() directly; this keeps the API compact yet extensible. Finally, there is no ClutterStage:fog so it should be added.
