Given a renderer and a display position in pixel coordinates, compute the world position and orientation where this point will be placed.
This method is typically used by the representation to place the point initially. For the Terrain point placer this computes world points that lie at the specified height above the terrain.

Given a renderer, a display position, and a reference world position, compute the new world position and orientation of this point.
This method is typically used by the representation to move the point.
