Geometry Boost List: [geometry] GSoc Project 2 Clarification

Hi,

With my PRs being (almost) wrapped up, I'd like to ask some doubts about
the other project (besides continuing to improve documentation, namely for
the arithmetic operations) I'd like to work on as part of GSoc '20 - Implement
support for non-cartesian geometries in convex_hull() either by adapting
existing algorithm and strategies (preferable) or implementing it as
different algorithm.

Assuming a coordinate system - the Polar coordinate system, for this, can
we not simply use the boost::geometry::transform function to convert
cartesian to polar coordinates and vice versa? In this case we can call
this function and implement the existing algorithm *convex_hull* suited for
cartesian coordinates and convert it back to polar coordinates once the
convex_hull is created in the cartesian coordinate system?
I can maybe tweak the transform function to incorporate the conversion of
ellipsoidal to cartesian system as well in order to extend its scope.

Thank You
