st: Make StScrollables' paint volume reflect the unconstrained view

Browse Source 
And constrain it in StScrollView instead (instead of falling back to an
infinite paint volume, as the actor as paint/pick impls, but no
corresponding get_paint_volume one).

Fixes artifacts with the AppView (and possibly other places) when paint
volumes are aggressively cached.
