makeSolidChainsSpt()
	colors according to solidColorScheme by calling makeSolidColorSchemeSpt()
	then calls makeSolidRenderSpt() (scripts.js)
		which does spacefill and applies colorLigand, colorSolvent.
	It uses getSolidRadii() (scripts.js) to set solidProteinRadius and solidNucleicRadius.

makeRenderSolidSpt() was the default currentView at startup.
	It spacefills only (no coloring).
Default startup changed to makeColoredSolidSpt().
