The region is yours; Xft doesn't retain a pointer to it.  If you're done 
with it at this point, you should destroy it.

This is normal; Andale mono has some intra-line leading added.

You should just drop support for core fonts; they're no longer necessary 
on any system.  Then you can switch elvis to a pure UTF-8 internal 
encoding and move translation to the file system interface where it 
belongs.

You'll also want to investigate the adventures of FcFontSort so that elvis 
can draw arbitrary strings of Unicode text.  Pango and Mozilla have 
examples of this particular function; I'm still considering how to wrap 
this in a convenient Xft package for mere mortal applications.
