New issue 971 by tu...@tudorgirba.com: Using Athens fonts is dead slow in Roassal http://code.google.com/p/moose-technology/issues/detail?id=971

Try this: [view := ROMondrianViewBuilder new. view shape label fontSize: [:x | x ]. view nodes: (10 to: 100). view open] timeToRun

On my MacBookPro i7 2.6 GHz this takes 23s.

The actual reason is that LogicalFont>>widthOfString: looks up the real font when the font is not yet cached. And this ends up looking for files on the disk.

What is even worse is that the widthOfString: is being called during the rendering cycle, so the whole image gets slow.
