[Etoys] Rehashing saves 600 KB

[Bert Freudenberg]

Hi folks,

Marcus Denker pointed out that rehashing reduces the image size quite  
a bit. I did

	Set rehashAllSets

and the saved image indeed is 650 KB smaller.

Can anyone think of a reason not to do this? Maybe there are some  
Sets/Dictionaries intentionally made larger than necessary for speed  
reasons?
