Hi Juan -

This is mostly to Juan but others might be able to help as well. I 
noticed that the Cuis fonts disagree in their pixel sizes significantly 
with that we get from the plain DejaVu true type fonts in Squeak. A bit 
of math reveals that at the (assumed) screen resolution of 96dpi a 12pt 
font should result in 16px high font (12*96/72 see Eqn. 3 in [1]). The 
corresponding Bitmap DejaVu 12pt font, however, is 19px high which would 
mean a screen resolution of 114dpi (19*72/12).

Is this choice intentional? Unfortunately, none of the pixel sizes for 
Bitmap DejaVu correspond exactly to a point size when assuming 96dpi.

The reason this is causing me grief is that I am trying to set up a 
mechanism for allowing people to drop the DejaVu fonts into their images 
and have any glyphs not part of the cuis fonts rendered in DejaVu 
truetype instead. I can probably get the truetype rendering to spit out 
a precise pixel size to match it but I think it'd be good if we had 
clarity on how these pixel sizes came into being.

Any insights appreciated!

Cheers,
   - Andreas
