problems with ly:font-load

[Werner LEMBERG]

Are you aware of the fact that

  (ly:font-load foo)

only loads an OTF font with the name `foo.otf'?  Additionally, the
font should contain OpenType tables `LILC', `LILY', and `LILF', or you
get a warning message.

In other words, this function is only suited to load lilypond's
`system' fonts and nothing else.  This should be mentioned in the doc
string.

Note that lilypond can't load any other font by itself; it uses uses
the fontconfig interface for everything else.
