 * Functions for moving segments.
 *
 * $Log: ksegmove.c $
 * Revision 2.0  1995/02/27  11:33:37  john
 * Version 2.0! No anonymous unions, Watcom 10.0, with no need
 * for bitmaps.tbl.
 * 
 * Revision 1.5  1993/12/02  12:39:36  matt
 * Removed extra includes
 * 
 * Revision 1.4  1993/11/12  16:40:23  mike
 * Use rotate_segment_new in place of med_rotate_segment_ang.
 * 
 * Revision 1.3  1993/11/05  17:32:54  john
 * added funcs
 * .,
 * 
 * Revision 1.2  1993/10/26  11:28:41  mike
 * Write common routine SegOrientCommon so all movement can pass
 * through the same routine to check for concavity, among other things.

 * Revision 1.1  1993/10/13  18:53:21  john
