possible alternative solution:

screen resolution is even too much. perhaps store it at some multiple of the 
displayed size (qMin(1.5*size, screenSize)) so that small rescales are fast 
and beautiful. when making it bigger, wait a period of time (to avoid constant 
resampling due to resizing) and resample the image. yes, this means that if it 
is resized more than 1.5 (or whatever factor) times larger than the current 
size it will get upscaled and look blocky until the resampling is complete.

this would give a nice compromise between memory usage, resize speed and how 
good it looks while resizing.
