New issue 3173 by address@hidden: beam thickness should depend on  
line thickness
http://code.google.com/p/lilypond/issues/detail?id=3173

Currently beam thickness is defined in terms of staffspace only. That gives  
unsatisfactory results.

Staffline thickness (measured relative to staff height) changes with staff  
size (it gets relatively thicker with smaller staff sizes), while beam  
thickness does not change (because it's defined in staffspaces). This leads  
to poor results: for staff-size 20 beamThickness/stafflineThickness ratio  
is 4.8, while for staff-size 10 it's only 2.9 - beams in small sizes appear  
thin.

In other words, "optical sizing" (described here  
http://lilypond.org/doc/v2.17/Documentation/essay/engraving-details#optical-sizing)  
doesn't work for beam thickness.
