class Enlighten::MergeGeometry

This is the very basic geometry description we operate on.

It's function is to provide a basic wrapper around simple arrays which is will release/delete with itself. You can construct it how you like, but there's some utils to allocate/delete arrays for you. The data is create/freeable in two halfs, geometry related stuff and tri-group/param related stuff.

Note

It intentionally doesn't handle "empty" geometry (no verts or indices or both). This case should be handled upstream.
