Vseries not handling two-channel rendering correctly

[brandon.scott@…]

The following bug report has been submitted:
Platform:        Windows-10-10.0.17134
ChimeraX Version: 0.9 (2019-03-08)
Description
Two channel rendering as a sub ID (ie 1.1 and 1.2) forces to one channel when playing as a vseries with one as a volume and the other as either a surface or mesh.

Fixed I think in tonight's builds.

The volume code has changed after your 2 month old ChimeraX was released so I get a a different error in today's build. I've fixed today's error and I can play a two channel series with one channel as surface style and the other as image style.
