Torch mod - formerly mod "Torches"
======================

(c) Copyright BlockMen (2013-2015)
(C) Copyright sofar <sofar@foo-projects.org> (2016)

This mod changes the default torch drawtype from "torchlike" to "mesh",
giving the torch a three dimensional appearance. The mesh contains the
proper pixel mapping to make the animation appear as a particle above
the torch, while in fact the animation is just the texture of the mesh.
