[Therion] A totally unreasonable request

I'd like Loch to be able to present in higher resolution as well, although
for me not such a high priority (as some other 2D presentation functionality
that is missing from the Therion palette).

Perhaps related, I'd like to be able to overlay multiple surface images at
one time, say topo map, geology, aerial photo, or multiple of each, some
covering the entire 3D model and some covering only part.

It would be a good step along the way if only one image could be displayed
at a time, and they could be toggled via the Loch interface.
