Change History (most recent first):
<13> 7/31/91 JL Updated Copyright. Restored Comments.
<12> 1/29/91 JL Changed parameter name of PixMap32Bit to from offscrrenPixMap to
pmHandle.
<11> 1/28/91 LN Checked in Database generate file from DSG. Grouping enums into
groups of 20.
<10> 1/25/91 stb JDR: add const on non-VAR parameters
<9> 1/15/91 KON Change useMFTempBit to UseTempMemBit. [csd]
<8> 11/28/90 JL Put formal parameter names back.
<7> 11/4/90 dba shortened inline for OffscreenVersion; use (void) instead of ();
got rid of some extraneous parameter names
<6> 10/990 JAL Changed __Safe_Link to _CPlusPlus.
<5> 9/1/90 dvb Beautify.
<4> 3/29/90 KON Put parameter size (in bytes) in high word of d0, trap selector
in low word.
<3> 3/27/90 KON Added useMFTemp flag, keepLocal flag, and prototypes for
selectors 19-23.
