**              resulting SVG output which limits its max-width.
**
**    -th       Process the input using TH1 before passing it to pikchr.
**
**    -th-novar Disable $var and $<var> TH1 processing. Only applies
**              with the -th flag.
**
**    -th-nosvg When using -th, output the post-TH1'd script
**              instead of the pikchr-rendered output.
**
**    -th-trace Trace TH1 execution (for debugging purposes)
**
** TH1 Caveats: the built-in TH1 commands make some assumptions about
** HTML escaping and output which do not apply via this
** command. e.g. some commands will output directly to stdout, rather
** than the output buffer this command requires. Improvements in that
** regard are under consideration/construction.
