Using emacs-snapshot-20090207, the text display becomes very ugly when
set via:

(set-default-font "DejaVu Sans Mono-10")

However, if the font is set via the menu bar: Options->Set Default Font

then the fonts look good (i.e., with proper anti-aliasing).

If the frame is already using an XFT font, doing

 (set-face-attribute 'default (selected-frame)
                     :font "DejaVu Sans Mono 10")

will give an XFT (anti-aliased) version of DejaVu Sans Mono.  If the
frame is using an X font, the same code gives the X version of DejaVu
Sans Mono.

Doing

  (modify-frame-parameters (selected-frame)
     (list (cons 'font "DejaVu Sans Mono 10")))

always returns the X version.  This discrepancy is due to the use of
font_open_by_name instead of font_load_for_lface.

I don't think there is anything that need to be corrected, apart from
giving the XFT driver a higher priority; I've just done that.
