Hi,

First, I've kept your whole message as a reply,
because (on my computer at least) while I received
your direct mail ok, the PD list archives and the
digest message I got just show it as:

Thanks for sending this, I will definitely have a go
with it when I have some time. I agree it should be
added to Gem if possible.

Yes I think what IOhannes meant was you could use
"multiple_window" to generate reflections for flat
surfaces. Similar to pix_snap2tex but you could use
the correct viewpoint.
