-%% notes from old dyn code.

-% `f' obviously has a _lot_ bigger slant than `p' (see Wanske p.239).
-% However; perhaps we need two f symbols:
-% - a super-slanted one used in `f', `mf', `sfz', `sf'
-% - a more normal-slanted in `ff', `fff', `fp', `fp' (see Wanske p.241)
-%
-% Looking at professionally typeset music reveals that typesetters
-% are somewhat unsure about slanting in `mf', `fp', `sfz'
-%
-% `f' and `p' (in any combination) are a lot (factor two) fatter than
-% `s', `m', and `z'. Sometimes the `m' and `z' are a bit fatter than
-% `s'.
-%
-% Chester, Breitkopf suggest smaller sizes of these other glyphs,
-% using the x-height as reference point.
