Re: Font size

[Ray <rehenry-at-up.net>]

Fred and Charles

I played with this to ensure that Charles got a full window of tkemc with
tkemc.  This is a 640x480 TkEmc.  I used 8 font size which is pretty small
10 would be better but the text window will run off the bottom a bit if
there are any panels on the screen.

I put a note below about where to change

This line above is the place to change from 8 to 10.  Since there is no 8
bold the ten will be much clearer.  10 just makes the buttons a little
taller.
