You can specify to use your custom fonts. The fonts will be defined in the header. Every definition of font have the folowing syntax:
"n" have to be a number between 0 and 9.
For exemple : ©!#1=tiosfont2!: the text written after a !#1! will be drawn as the middle font.
Then, the classic tags !#1!, !#2!, ..., !#9! can be inserted in the text to change the current font.
