i don't see anything called "stencil-width" in grob.cc...

I don't want to read the value of extent, i want to modify how it's
calculated in case of noteheads.
I suppose that noteheads X-extent is wrongly calculated now.  Judging
by this 
http://lilypond.googlecode.com/issues/attachment?aid=-4756087064344904294&name=test.png&token=22aa1208ff6775e1780efcedc7e7e841&inline=1
, all noteheads are assigned the same X-extent, even though the glyphs
have different widths.
Or maybe i don't understand how it works...
