Perhaps this can be set based on the fraction of the target shrink time.

Pick a target shrink time, say, 1.5 seconds.  Remember the long seconds 
or the milliseconds at the start.  At this point of your code get it 
again and find out how much time has passed.  Get the fraction of the 
target time.  Get the same fraction of the dimensions rounding down.  
(Make sure the first one shrinks some amount.)  Use that.

Set the send delay to the target time divided by the largest dimension 
and send _before_ the computation.  If you need to get mouse clicks 
during that time, perhaps you can set the delay to 5 ms and send it 
after the computation, just before the handler end; you may want to 
check that the new size is not the same as the old one in this case.

Slow computers will see a stepwise shrinking and fast computers will 
see a smooth shrinking.  If the engine changes, this will adapt.  The 
number of steps will also adapt to other sends and callbacks keeping 
things busy.
