/**
* Each ternary raster operation code represents a Boolean operation in which the values of the pixels in
* the source, the selected brush, and the destination are combined. Following are the three operands
* used in these operations.
*
*
* Raster-operation code meaning
* Operand Meaning D Destination bitmap P Selected brush (also called pattern) S Source bitmap
*
* Following are the Boolean operators used in these operations.
*
* Boolean operator meaning
* Operand Meaning a Bitwise AND n Bitwise NOT (inverse) o Bitwise OR x Bitwise exclusive OR (XOR)
*
* All Boolean operations are presented in reverse Polish notation. For example, the following operation
* replaces the values of the pixels in the destination bitmap with a combination of the pixel values of the
* source and brush: PSo.
*
* The following operation combines the values of the pixels in the source and brush with the pixel values
* of the destination bitmap: DPSoo (there are alternative spellings of some functions, so although a
* particular spelling MAY NOT be listed in the enumeration, an equivalent form SHOULD be).
*
* Each raster operation code is a 32-bit integer whose high-order word is a Boolean operation index and
* whose low-order word is the operation code. The 16-bit operation index is a zero-extended, 8-bit
* value that represents the result of the Boolean operation on predefined brush, source, and destination
* values. For example, the operation indexes for the PSo and DPSoo operations are shown in the
* following list.
*
*
* Raster-operation examples
* P S D DPo DPan 0 0 0 0 0 0 0 1 0 1 0 1 0 1 1 0 1 1 1 1 1 0 0 1 1 1 0 1 1 1 1 1 0 1 1 1 1 1 1 1
*
* The operation indexes are determined by reading the binary values in a column of the table from the
* bottom up. For example, in the PSo column, the binary value is 11111100, which is equivalent to 00FC
* (hexadecimal is implicit for these values), which is the operation index for PSo.
*
* Using this method, DPSoo can be seen to have the operation index 00FE. Operation indexes define the
* locations of corresponding raster operation codes in the preceding enumeration. The PSo operation is
* in line 252 (0x00FC) of the enumeration; DPSoo is in line 254 (0x00FE).
*
* The most commonly used raster operations have been given explicit enumeration names, which
* SHOULD be used; examples are PATCOPY and WHITENESS.
*
* When the source and destination bitmaps are monochrome, a bit value of 0 represents a black pixel
* and a bit value of 1 represents a white pixel. When the source and the destination bitmaps are color,
* those colors are represented with red green blue (RGB) values.
