I made sure to include in Grafx2 only fonts that can be :
- freely distributed : whenever the Grafx2 archive is copied, or the program is installed
- freely used : You can paint text in your images without sharing copyright with the font creator or having to comply with a specific license.
The fonts with prefixes "PF" are made by Yusuke Kamiyamane, license : "These fonts can be used free for any personal or commercial projects."
Your installation of Grafx2 should include a file doc/PF_fonts.txt which acknowledges the author and states the license :

I just checked, and the GNU public license is not perfect for fonts, so I hereby release 8pxfont.png to the public domain : Anybody can do anything with it.
