*
* 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
* Initial revision
