Our stack has a very few bits of code that still use the geom package. In particular they use the convexHull function. geom has been superseded by sphgeom (which is written in C++ instead of python) and contains ConvexPolygon.convexHull. Update the code, paying careful attention to API differences, if any.
This is driven by a desire to repurpose the geom package for afw geometry primitives (
RFC-460) and to retire obsolete and unmaintained code.
