/*
 * height_width.c
 *
 * Lib module to be inherited into humanoid npcs.
 * It allows width and height descriptions to be
 * set directly without having to juggle height
 * and width props.
 *
 * CAVEAT: You _must_ call set_height_desc() first, as the values generated
 *         by set_width_desc() are dependant on those values produced by
 *         set_height_desc(). You can call in either order, but calling
 *         set_height_desc() after may screw up the values generated by
 *         set_width_desc(). To be safe, use set_size_descs().

 *                it is important to first set the height before you set the
 *                width. Alternatively, use set_size_descs() to set both.
 *                To see all possible height descriptions, do:

 *
 * Arguments    : string str - the desired height description.
 * Returns      : int 1/0 - success/failure.
