WebVR : Enable VR Mode for Aquarium

[shaoboyan]

Currently, WebVR 1.1 is supported by lots of browsers, like firefox, chrome, etc. However , there isn't any ready benchmark or workload for browser based VR experience.
Since Aquarium is one of the famous benchmark of WebGL, we'd like to align it as the benchmark for browser based VR experience, too.
I've worked out the prototype of VR Mode for Aquarium now. And if you agree, I''m very happy to contribute this !

It's open source so feel free to do whatever you want with it.

If you'd like to check it in here I think at first I'd prefer it be in a different folder. The aqurium is in the aquarium folder, maybe the WebVR version could be in aquarium-vr

@greggman thx !

@greggman do you think it is the time aquarium-vr could merge into aquarium ? If not, is there any gap need to be filled?
P.S. aquarium-vr now support all of the feature aquarium has and doesn't affect normal aquarium rendering path.

Thx !

What do you think about having a menu inside VR? Is that hard? (note I haven't looked at WebVR yet. I guess it probably doesn't support HTML in VR?). I also noticed the rays don't work in VR. Maybe just turn them off if in VR mode if they're not going to be fixed?

@greggman thx for replying!

1. Have a menu inside VR : it is possible but need to include a-frame library to do it. I'd like to added a menu UI layer(when user click button, a UI layer will pop up, rendering scene will disappear, and user could use controller to modify it, close UI layer and see rendering scene again).
   Or I could try to write the whole UI with WebGL(some workloads, like create simple button, slides bar, controller model, controller ray and chosen effect... but I think it is possible for user to modify variable and see the result immediately). It is appreciate if you offer your suggestion :)
2. Thx for your info about Rays issue. I think I'd like to fix this to align with original aquarium. Would you offer some suggestion on this issue ?
   P.S. Is rays issue means light ray in aquarium? I can see these light ray in vr mode. Could you give some more description of this issue? thx !
