Change History (most recent first):
<1+> 1/22/90 JRM update to Craig's "last" revision
<1.2> 10/16/89 CCH Incorporating changes from Craig Carper.
<1.1> 10/11/89 JSM Fixed BEDraw so that it doesn't indiscriminately call GetGDevice
and SetGDevice without checking for color.
<1.0> 8/3/89 CCH Adding to EASE for Big Bang build as PACK ID=1.
