These types provide fixed-point representations of distances, angles, positions, vectors, and rotations in 3d space. WAngle (and WRot) represents 360 degrees in 1024 units. WRange (and WPos, WVec) represents 1 cell in 1024 units. Distance types in yaml can be written as <cell>c<subcell>, e.g. "4c512" for 4.5 cells.
