- _d_i_s_t expects the distance from the viewpoint to the world space
- origin.
-
- _a_z_i_m expects the azimuthal angle in the x-y plane, measured from the y
- axis. The azimuth angle is the viewing angle of the observer.
-
- _i_n_c expects the angle of incidence in the y-z plane, measured from
- the z axis. The incidence angle is the angle of the viewport
- relative to the z axis.
-
- _t_w_i_s_t expects the amount that the viewpoint is to be rotated around the
- line of sight using the right-hand rule.

- ppppoooollllaaaarrrrvvvv defines the viewer's position in polar coordinates. It sets up a
- right-hand world coordinate system with x to the right, y straight up,
- and z towards the viewer. The line of sight extends from the viewpoint
- through the world space origin. All angles are specified in tenths of
- degrees and are integers.
-
- The matrix computed by ppppoooollllaaaarrrrvvvv premultiplies the current matrix, as
- specified by mmmmmmmmooooddddeeee. ppppoooollllaaaarrrrvvvv is typically called only while mmmmmmmmooooddddeeee is
- either MMMMSSSSIIIINNNNGGGGLLLL or MMMMVVVVIIIIEEEEWWWWIIII.
