Change History (most recent first):
|
|
|
|
<11> 7/31/91 JL Updated Copyright. Restored Comments.
|
|
<10> 2/4/91 JL Added pixPurgeBit, noNewDeviceBit, useTempMemBit, keepLocalBit,
|
|
pixelsPurgeableBit, pixelsLockedBit, mapPixBit, newDepthBi,
|
|
alignPixBit, newRowBytesBit, reallocPixBit, clipPixBit,
|
|
stretchPixBit, ditherPixBit, gwFlagErrBit.
|
|
<9> 1/30/91 JL changed parameter name of PixMap32Bit to pmHandle.
|
|
<8> 1/28/91 LN Checked in Database Generated File from DSG.
|
|
<7> 1/15/91 KON Change useMFTempBit to UseTempMemBit. [csd]
|
|
<6> 11/4/90 dba use shorter inline for OffscreenVersion
|
|
<5> 4/3/90 ngk Fixed definition of OffscreenVersion
|
|
<4> 3/30/90 KON High word of D0 contains number of parameters, low word contains
|
|
selector for all GWorld calls.
|
|
<3> 3/27/90 KON Added useMFTemp flag, keepLocal flag, and prototypes for
|
|
selectors 19-23.
