Alright, that probably asn't what you were looking for.  I may have the
macros but I'd need to clean them up a bit.  Just for clarification .... you
mentioned a NSEW sytem of camera position and orientation.  I wouldn't mind
seeing the source for that.  And as for tilt and pan ... Assuming left hand
coordinates and the camera is at the origin looking at +z.  Pan is the
rotation of the camera along the local y axis ( left to right) and tilt
along the local x (up and down).
