[chimerax-users] Surface caps only colored interactively

[Tom Goddard]

I made the view and clip commands update the clip cap surfaces immediately so that the "wait 1" command in your ChimeraX script will no longer be needed to get the cap coloring to work.  This will be in tomorrow's daily build and in ChimeraX 1.2 which we plan to release at the end of the month.

But this case and a few others (like changing map contouring level) only cause updates to the surfaces when the frames are redrawn.  We need to figure out a better compromise between speed and obvious behavior.
