You cannot do that as flex is single threaded and convertToImage will take
all processing power... So even if you put a progress bar it will jump from
0 to 1...
I have seen a tutorial where this functionality is broken in chunks with
small modification to the encoding class but cannot remember where...
Anybody else remembers the link?
