91 % "f" obviously has a _lot_ bigger slant than "p" (see Wanske p.239)
92 % however; perhaps we need two f symbols:
93 % - a super-slanted one used in "f" "mf" "sfz" "sf", and
94 % - a more normal-slanted in "ff" "fff" "fp" "fp" (see Wanske p.241)

97 % are somewhat unsure about slanting in "mf", "fp", "sfz"
