Module Name:
ropblt.c
Abstract:
This module contains code to deal with ROP3 codes
Author:
07-Jan-1994 Fri 11:04:09 created
27-Jan-1994 Thu 23:42:09 updated Bascially re-write the codes, make up our own ROP3 to ROP2s generator and mixer. Cloning the surface object as necessary, some of ROP4 to ROP2 (Rop3ToSDMix[]) are hand twiks so that it can handle the one which we can not handle before (ie. multiple destinaiton usage cases)
16-Mar-1994 Wed 11:21:45 updated Update the DoMix2() so the SRC aligned to the destination only if the source is not psoMask

// 18-23: Each has 6 bits, lower 4 bits denote MIX2 operation code (one

//
// Bit 24-25: 2 bits indicate the total MIX2_xxx operation codes minus 1,
// 00=1, 01=2, 02=3, 03=4, maximum will be 4 Mix2 operations
//
// Bit 26: Not Used
// Bit 27: Not Used
// Bit 28: Not Used

// needed to stored the PAT/SRC Mix2 operations.
// Bit 30: Flag MIX2F_MUL_SRC to indicate multiple source operations
// are present in the Mix2s.
// Bit 31: Flag MIX2F_MUL_DST to indicate multiple destination operations
// are present in the Mix2s.
//
// The Rop3ToSDMix[] is a DWORD array. each DWORD (SDMix) is defined
// above. The Rop3ToSDMix[] only list the first 128 of the ROP3 code, the other
// 128 Rop3 codes (128-255) can be obtains by 'Rop3ToSDMix[Rop3 ^ 0xFF]' and
// the result of the Rop3 must be complemented.
//
// Since all Rop3/Rop2 codes are symmetric, we can complement the Rop3/Rop2
// result by complementing MIX2_xxxx (0->15, 1->14...,7->8).
//
// The [!x] in the Rop3ToSDMix[], indicates the following
//
// !: Indicates MIX2F_MUL_DST bit is set for the ROP

Routine Description:
This function is responsible for doing a device copy of a bitmap with/without tiling and activating the proper Rop2
Arguments:
pPDev - Pointer to the PDEV
psoDst - pointer to the destination surface object
psoSrc - pointer to the source surface object
pco - Pointer to the CLIPOBJ
pxlo - the translate object from the source to the destination
prclDst - the output destination rectangle area
prclSrc - the source rectangle area
pptlSrcOrg - brush origin for the source rectangle, if this is NULL then prclSrc will not have to be aligned on the destination
Mix2 - a rop2 mode 0 - 0x0F
Return Value:
BOOLEAN
Author:
08-Feb-1994 Tue 16:33:41 updated fixed ptlSrcOrg problem, we need to modulate with source size before it get used.
27-Jan-1994 Thu 23:45:46 updated Re-write so that it can handle the tiling more efficient.
