Review request for Plasma.


Summary
-------

with the free resizing patch it occurred that framesvgs are quickly generated and regenerated each micro resize during the scale
in that case (as fredrik immediately noted :) caching becames very expensive due to disk writes and qimage conversions
this patch adds a timer that saves the rendered frame only when it stayed still for some time, so ideally caching only the size before and after the resizing
