LyX X fonts and the command line

[Lior Silberman]

AFAIK, the only way to select (X display) fonts in LyX is through the
lyxrc mechanism ( \screen_font_* settings ).

I would like to use LyX from several different displays, each of which has
different fonts available (as xfontsel testifies). Thus, it would help if
there were command-line options for these settings, overriding
lyxrc. Note there are various (command line) options for changing the
colours (according to the man page).

If this only requires superficial changes to the code, I'll be happy to
make them myself.

Thanks,
Lior.
