* This function, with the help of r_plane.c and r_bsp.c, supports generalized
* scrolling floors and walls, with optional mobj-carrying properties, e.g.
* conveyor belts, rivers, etc. A linedef with a special type affects all
* tagged sectors the same way, by creating scrolling and/or object-carrying
* properties. Multiple linedefs may be used on the same sector and are
* cumulative, although the special case of scrolling a floor and carrying
* things on it requires only one linedef.
*
* The linedef's direction determines the scrolling direction, and the

* edge around a sector can be used to control the direction of the sector's
* scrolling, which is usually what is desired.
