 the box to have it render on the newly selected raster map, it stays at
 z=0 below. "Height above surface" there also appears to work as a
 multiplier, not in map units? but of what? the archsites map is not 3D.

 currently if you type e.g. `325` degrees in the box and move the slider
 you can see where it crosses over itself and the geometry inverts.
 interesting, but not really usable.

 I tested both of these in trunk, seems ok.

 I also tested adding points without a surface, the first time I again got
 the repeating "Gtk-CRITICAL **: gtk_range_set_range: assertion `min <
 max'" in the terminal, but quitting the gui and restarting it then worked.
 I'll try to test that more later.
