Render allows both vertical and horizontal escapements.

Render provides delta positioning (x and y) between any sequence of 
glyphs, I haven't exposed that protocol in any API yet.  I haven't seen 
many X applications use the core equivalent very successfully so I was 
waiting for suggestions on what the API should look like.  Xft has the 
advantage of knowing the glyph escapements, so it could take an array of 
positions and compute a minimal encoding for that.
