I suppose. However, this would probably complicate the bookkeeping
and have a negative effect on performance.
Consider, for example, an instance where during the freeze period you
hide one object and add another in its place. The library would have
to clear the area where the old object was and draw the new one.
Overlapping objects would be complicated -- adding a box around
another object (admittedly an unlikely case) would be messy -- you'd
have to analyze the geometry and positions of every object to make
sure that you weren't unintentionally overwriting something.
