[Chimera-users] "add-surface" button

    Yeah, the demand for 3-D voxell images may be low at the moment.
But I would still consider adding some kind of "add-surface"
button to volume-viewer when in surface or mesh-mode.  Steve McQuinn
made a very pretty picture of phageT4 using a red colored surface
in the interior, and a green one on the exterior and it is pretty.

(I hope having multiple surfaces doesn't cause end-capping to crash.)

I'll try to keep it down to a dull roar for a little while.
