- _v_o_b_j expects the transformations that map the displayed objects to
- world coordinates.
-
- _s_x expects the x coordinate of the screen point to be mapped.
-
- _s_y expects the y coordinate of the screen point to be mapped.
-
- _w_x returns the corresponding x world coordinate.
-
- _w_y returns the corresponding y world coordinate.

- mmmmaaaappppwwww2222 is the 2-D version of mmmmaaaappppwwww. _v_o_b_j is a viewing object that defines
- world space. It contains only routines that affect the model-view
- matrix, the projection matrix, or the viewport specification. _s_x and _s_y
- define a point in screen coordinates. _w_x and _w_y return the corresponding
- world coordinates. If the transformation is not 2-D, the result is
- undefined.
