I'm a bit confused to which does what: so HG POV, is able to create displacement
on meshes, right? is this macro for standard POV (3.8?) able to do this as well?
if both are, what would be some advantages of using one over the other in
various situations?  I hope some natively shipped feature will finally come out
of all this. Thanks for your generous efforts!
