-
-#if PSZ == 24 && (MROP) == 0
-
-/* The default macros are defined in mergerop.h, and none of them are
- really appropriate for what we want to do.
-
- There are two ways of fixing this: either define SLOW_24BIT_COPY
- to copy pixel by pixel, or (by default) use the following macros
- modified from mergerop.h
-
- MROP_SOLID and MROP_MASK are defined for each of the operations,
- i.e. each value of MROP.
-
- There are special cases for Mcopy, McopyInverted, Mxor, and Mor.
- There is a completely generic version for MROP=0, and a simplified
- generic version which works for (Mcopy|Mxor|MandReverse|Mor).
-
- However, the generic version does not work for the 24-bit case
- because the pixels cannot be packed exactly into a machine word (32
- bits).
-
- Alternative macros MROP_SOLID24 and MROP_MASK24 are provided for
- the 24-bit case. However, these each copy a single *pixel*, not a
- single machine word. They take an rvalue source pixel, an lvalue
- destination, and the pixel index. The latter is used to find the
- position of the pixel data within the two words *dst and *(dst+1).
-
- Further macros MROP_SOLID24P and MROP_MASK24P are used to copy from
- an lvalue source to an lvalue destination. MROP_PIXEL24 is used to
- assemble the source pixel from the adjacent words *src and
- *(src+1), and this is then split between the destination words
- using the non-P macros above.
-
- But we want to copy entire words for the sake of efficiency.
- Unfortunately if a plane mask is specified this must be shifted
- from one word to the next. Fortunately the pattern repeats after 3
- words, so we unroll the planemask here and redefine MROP_SOLID
- and MROP_MASK. */
