Smoothing sloped beams?

[Doug Asherman]

Hi:

This may not be a lilypond issue, but I'm asking the list anyway.

I've been asked to provide online samples with "smoother" beams; the 
complaint is that the sloped beams are jagged-looking (even though they 
look fine when they're printed out).

Is there a tweak that will make the beams a little less jagged? Would 
this entail picking up new fonts (or making new fonts)?

Thanks for any help.

Doug
