Any script that changes the molecular view is supposed to use
doMolViewSpt(). However, there are lots of calls to scriptToJmol()
and some to unchangedScriptToJmol().

doMolViewSpt() in scripts.js
	handles hiding, dots, hover mode
		calls scriptToJmol()

scriptToJmol(spt) in top.js
	handles busy for JSmol
	handles labels
	adds empty baskets (markBrokenEnds)
		calls unchangedScriptToJmol(spt)

unchangedScriptToJmol(spt)
	calls jmolScript(spt) from Jmol2.js
