I think the hardest part is designing the interface.
How would you specify the frame to dump ?
Consider that the same frame number can result
in different rendering due to gotoframe and actions
and looping.
Maybe the easiest solution is adding a keystroke to dump
current frame, but that would be about equivalent to
using an external software to take a screenshot...
