 * Revision 1.5  95/04/27  23:01:16  bill
 * Major ci for 3.0 Alpha (new: pgeneral, dm)
 * 
 * Revision 1.4  95/03/21  14:50:22  bill
 * Adding the global opacity setter
 * 
 * Revision 1.3  1995/03/10  19:03:01  bill
 * Ci for beta release of v2.1 dvs -> dsys change
 *
 * Revision 1.2  1995/03/10  18:43:29  bill
 * Ci for beta release of v2.1
 *
 * Revision 1.1  1995/03/06  10:24:34  bill
 * Initial revision
 *
 * Revision 1.4  1994/11/09  17:49:06  bill
 * texture type was int32 instead of uint8, read wronge
 *
 * Revision 1.3  1994/08/30  17:18:09  bill
 * Altered -t so it sets the background opacity to a given value (-ve is
 * default and preserves inta, rgba and svt opacity values, sets rest to
 * 255).
 * Also added sgi save -> rgba format.
 *
 * Revision 1.2  1994/05/13  12:08:51  bill
 * File name changing for release. pfile.h->pfile2.h, __pfile.h->__pfile2.h, ptools.h->ptools2.h, __ptools.h->__ptools2.h, filelib.h->filelib2.h, getparam.h->getprm.h.
 *
 * Revision 1.1  1994/04/15  15:43:18  bill
 * new pfile and ptools that cope with spheres lines text and polygons, also uses new FL extension pfl & PF extension dpf
