[PD-dev] more on the 12 point font mystery

[Hans-Christoph Steiner]

Hey,

I just added Windows picks of the fonttest.tcl.  If you at those  
images in sequence, you can see there are only really tiny variations  
on each platform, EXCEPT 12 point on GNU/Linux.  Strange, but that's  
the way it seems to be.

As for the existing size measuring code, I think it was part of the  
problem.  Plus if we can make it work on all platforms without any  
dynamic sizing, which is a great potential source of bugs, why not  
just hard code it?

I made two little movies to illustrate the issue:

http://pow.idmi.poly.edu/~hans/pdfonts/fonttest/normal.mov
http://pow.idmi.poly.edu/~hans/pdfonts/fonttest/bold.mov

As you can see in the movie, there is no dynamic measurement needed,  
the fonts are all very close one tk scaling is set to 1. Except, of  
course, the pesky 12 point on GNU/Linux.

If you are not part of the solution, you are part of the problem.
