-
-/* 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. */
