That's a bug in the module. If the user doesn't explicitly specify a
font, the module should use the current font, not some arbitrary
default. Especially as any setting which the module makes will persist
for subsequent modules.

If you can identify specific modules which behave this way, I'll fix
them (starting with d.vect).

I'm not sure that's a good idea. If we were to replace freetype with a
font path, the list could become huge (my WinXP system has 120 .ttf
files in C:/WINDOWS/Fonts, and that's just what comes with the OS or
with other packages which I've installed; I haven't explicitly
installed any additional fonts).

Instead, I'd suggest just removing the ->options field.
