Heatmap support

See original GitHub issue

Custom PoCs: NY foot trafic dataset, gecat dataset and WWI_ships dataset
Support for grid-alignment (NY dataset)
Bi-cubic interpolation
Isolines PoC
Support non-square windows
API
Support for limitting heatmap grid size based on zoom
Workarounds lack of OES_texture_float and OES_texture_float_linear. Important for mobile.
Automatic discovery of min/max values

Yes, there were multiple branches. The last one I think it is square-grid, but it also contains some unwanted changes to the sources.

I think that a merge would be too difficult at this point too. Rewriting the functionality while reading the diff of the branch is probably the easiest way.

You can read the diff here: https://github.com/CartoDB/carto-vl/compare/square-grid

The interesting parts that could be copied are on renderer.js and on the shaders.

Keep in mind that the branch never made a public API to configure the heatmap.

I believe this is the branch. Bear in mind that this way behind the master branch, based in code that no longer exists and probably with a lot of hacks just to proof the concept
