This documentation is now so out of date as to be possibly worse than
useless, as in, not only is it very incomplete, but now a lot of it
is actually incorrect.
What should be documented but isn't: advanced layer usage,
automatically created "CLICKED:" triggers, button disabling, more on
sticky/checkbox/radio buttons, the whole
question/answer/ql/followup/speaker/topic morass, turning off
logfiles, styled text in answers, how to cut down memory usage,
tool-relative hosts, issues when making CD-ROMs,
application and saved game icons,
much, much else.
