3d plains and textures

[Mike from CT]

I know these came up during the development of version 6, so this is just to put them on the common wish list....

Ability to define topography, separate from (or in addition to) relying solely on trackwork and tabletop.
And ability to ascribe different colors or textures to different parts of terrain (e.g add a river or road through a field.  (Simplest way would be to bring over to 3D attributes attached to 2d shape)

Also, option for shapes to follow terrain rather than create it.  (e.g. a road that runs down a hill.)
