"Could you specify:
* threads that share stems
* threads that must be, or may be fixed to a staff (upper or
lower)
* threads that may be, or must be auto-switched"
As currently written:
* All threads within one voice share stems and slur/stem
direction, no others do.
* No thread is fixed to a staff now, but that may be necessary
for rests when I get closer to final layout.
* All notes are at thread level and must be autoswitched,
independently.
* noteHeadStyle and fontSize settings for one Thread must not
affect any other thread
* The sL and sR TeX macros are defined in the envelope file:
\newcommand{\chancsymb}[1]{{\fontfamily{pzc}\fontshape{it}%
\fontsize{12}{12pt}\selectfont #1}}
\newcommand{\sL}{\chancsymb{L}}
\newcommand{\sR}{\chancsymb{R}}
