[Sugar-devel] More information on font scaling problem

[James Simmons]

Gary,

Thanks for doing this.  I wish I could say it cleared things up but I 
feel more confused than before.  You say these are both XO's with 
different versions of Sugar.  I thought that the font behavior on the XO 
was consistent, no matter what version of Sugar you used, but that you 
needed to use the SUGAR_SCALING environment variable in other places to 
make the fonts look OK.  That doesn't make sense because the zoom factor 
should be 72, meaning that any font number you put in would be 
multiplied by .72 and truncated to the next lowest integer.  Which is 
just the opposite of what you'd want to do, because it's the XO that has 
the font too big, not my development environment or SoaS.

Even the .84 one doesn't look right to me.  When I run sugar-emulator on 
Fedora 10 the font looks *much* smaller than that.

Maybe sugar-emulator *is* providing SUGAR_SCALING but instead of 100 it 
is using 72?
