glsl-colormap

[dy]

We can borrow some ideas from glsl-colormap, pretty nice collection.

Definitely worth porting them all over

@dfcreative so lets meet up and figure out how to script those colormaps and port them over into the JSON blobs we have here

[dy]

I can devote some time to it, that should not be difficult. Although @etpinard had an idea that maybe we better remove colormap from plotly dist, since we duplicate them as a constant.

[etpinard]

Can we just reuse https://github.com/plotly/plotly.js/blob/master/src/components/colorscale/make_color_scale_func.js

[bpostlethwaite]

@etpinard yep you only need the scales. I actually want to add this to the library independently from plotly.js. I didn't even realize plotly.js still used colormap

[etpinard]

Only gl3d surface and mesh3d uses colormap I believe. We should definitely keep it out of the regl2d rewrite.
