Int 2F Fn AC07 - Qrip/tsr - Get Font Directory [V]
AX = AC07h
DI = 1092h
Return: DX:BX -> 80-byte internal buffer containing ASCIZ font directory name
Notes: if DI <> 1092h on entry, QRIP chains the call
the application may change the font directory by overwriting the
returned buffer, ensuring that it does not exceed 80 bytes incl. NUL
if changed, the new path will not become effective until the graphics
screen is reinitialized
