I haven't installed the OM development stack yet, and I haven't installed
the geocaching patch.  Since PANGO_SCALE looks like a global variable, I
tried to find a global pango config file, and I couldn't find anything.  I
tried to set the PANGO_SCALE as a global shell variable, and no luck.

In your code snippet, it seems like that hard-coded "60" should be a
user-definable variable from the config screen or at least a config file.

I guess it's time for me to install the OM dev kit.

Thanks for the info. :)
