[CM] new-effects.scm crashes snd

[bil at ccrma.Stanford.EDU]

In new-effects.scm the only font mentioned that might
be a problem is the "built-in" X font (for stuff like
XC_crosshair).  In snd-motif.scm, there are two uses
of the font "9x15" -- this is a very old (but very good)
fixed width font that may now be relegated to the
X miscellaneous fonts package.  You may have
to install it by hand, xorg-x11-fonts-misc in
Fedora.  I need to add some other choice there --
everywhere else, the code uses various user-chosen
fonts, I think.
