Upon further thought: traditional engraving is made by a combination
of real engraving/cutting and stamping in a metal plate.
One would think that whether a point on a metal plate is depressed in
a stamping process, depends on the distance to the the stamp. That
would mean that the shape of the depression is the Minkowski sum of a
small circle (of radius blot_diameter) and the outline of the
stamp. In other words: rounded outside angles, sharp inside angles.
For cutting, one could vary the pressure on the cutting tool to
produce lines that are thinner than blot_diameter; also it should be
possible to produce sharp outside corners for symbols that are cut
(bar lines, slurs, staff lines, beams).
Anyway, this is all theoretical muttering: I'll take out my magnifying
glass tonight to have a look.
