Checked it out.  The way pango does it is by only caching the pointer to
the returned XFontStruct, and maintaining a reference count for each
structure (in order to handle the freeing of these structures later).  That
could work here as well, if we wrap the XFree.*Font.* calls as well.  

However, my cursory tracing/sniffing seems to indicate that not that many
packets get wasted on redundant calls to the font functions, so I'm not
sure this is worth doing.
