Will merge with master after #652 is merged, then we can work on this PR.

That's a horrible idea. gl2d subplots are sloooooooooow. Even though individual gl2d subplots can display far more points than their svg counterpart, graphs with 4+ gl2d subplots are incredibly slow to render at the moment.

Okay, so I wasn't crazy when I was seeing avg run times that were greater in webgl vs non webgl subplots.

I was only doing this for a user who asked for this feature to speed up their scatterplotmatrices. I suppose I'll just let them know all this

@Kully Probably a good idea to point plotly.py gl2d users to plotly/plotly.js#130 for more info on the current limitations.

Disregard that deleted comment, I read @etpinard's comment too fast. Sweet, thanks chiming in on this one.

Cool, I have no problem adding this in now. It's just an minor inconvenience wrt conflicts, that's all.

If it's slower tho, i should abandon the PR no?
