Feature Request: TesselationBuffer

[CraigglesO]

I have a mapping engine that uses a spherical projection:

Your library benefits from the idea of pre-"earcut"-ing the geometry and storing the resulting index data. However, with the spherical projection, at low zooms I also have to tesselate the geometry to properly wrap around a sphere creating a small excess of indices and vertices.

I wrote an earclip library that add's a tessellation step.

Since you still need to build the geometry correctly incase you may only want the polgyon data itself, the excess vertices should be stored in a separate table.

This is why I propose adding one more buffer table (that is optional) named TesselationBuffer that stores the excess Int32 values.
