Squeak 3.7beta 5905

I pick a morph created long ago and drop it on a ProjectViewMorph
and a got an error saying that 'fontSize:' is unknown.  With the
debugger I found that the problem was that the morph I dropped
contains old fonts 'ComicBold' not on my image.

IIRC, somebody (may be Ned) posted some code to change the old fonts
by the new ones...but may by I dreamed...or the code was'nt for that..? 

Any body remember...references ?
