[Cuis-dev] Adding Single Font / Morphic Update

[Juan Vuletich]

Hi Eric,

This message is again with cc to you. I hope you get it this time (as I 
just said in a separate message, I cleared the "nodupes" mail list 
option for all subscribers, hoping to solve this lost messages problem).

The fonts in Cuis are drawn with BitBlt, with the 
anti-aliasing-text-with-BitBlt technique I developed many years ago and 
was adopted by Squeak and Pharo. But the glyphs were built rather 
recently. That's maybe why they look better. Rounded window corners and 
gradients also look better in Cuis, because I made them so. Still they 
are drawn using BitBlt.

Still, try the included TrueType fonts (drawn using VectorGraphics as I 
said in the message Phil was kind enough to forward again). They look great.

Yep. That would be a nice contribution.

Cheers,
