Module Name:
stretch.c
Abstract:
This module contains all the StretchBlt/BitBlt codes which handle halftoned
sources
Author:
09:12 on Thu 23 May 1991 -by- Lindsay Harris [lindsayh]
Created stub for DanielC to fill in.
24-Mar-1992 Tue 14:06:18 updated -by- Daniel Chou (danielc)
Calling halftoneBlt(), CreateHalftoneBrush() in printer\lib directory.
17-Feb-1993 Wed 13:07:53 updated -by- Daniel Chou (danielc)
Updateed so that engine will do all the halftone works, and add
DrvBltBlt(SRCCOPY/SRCMASKCOPY) to do the halftone
01-Feb-1994 Tue 21:49:53 updated -by- Daniel Chou (danielc)
Re-written so it handle the BitBlt(ROP4) correctly. not just SRCCOPY
but anything deal with non halftone compaible source
[Environment:]
GDI Device Driver - Plotter.

Code error for BMF_4BPP/BMF_8BPP DestFormat, it should not use ||
operator but && operator, also the 'i' is mistake assigned as 4, it
should be SrcBmpFormat dependent.

Fixed the iSrcType checking, since the Engine can pass a 0 to us

Revision History:
01-Feb-1994 Tue 21:51:40 updated -by- Daniel Chou (danielc)
Re-written, it now will handle any ROP4 which have soruces involved
either foreground or background. It will half-tone the source first
if it is not compatible with rasdd destiantion format, then it passed
the compatible source to the EngBitBlt()
17-May-1995 Wed 23:08:15 updated -by- Daniel Chou (danielc)
Updated so it will do the brush origin correctly, also speed up by
calling EngStretchBlt directly when SRCCOPY (0xCCCC) is passed.
