Jonas Dreßler 7abf0f1e2d clutter/stage: Set viewport without getting the last allocation
When getting the last allocation using
clutter_actor_get_allocation_box(), Clutter will do an immediate
relayout of the stage in case an actor has an invalid allocation. Since
the allocation is always invalid when the allocate() vfunc is called,
clutter_stage_allocate() always forces another allocation cycle.

To fix that, stop comparing the old allocation to the new one to find
out whether the viewport changed, but instead use the existing check in
_clutter_stage_set_viewport() and implement the behavior of rounding the
viewport to the nearest int using roundf() (which should behave just as
CLUTTER_NEARBYINT()) since we're passing around floats anyway.
