/**
 * The BinaryRasterOperation Enumeration section lists the binary raster-operation codes.
 * Rasteroperation codes define how metafile processing combines the bits from the selected
 * pen with the bits in the destination bitmap.
 *
 * Each raster-operation code represents a Boolean operation in which the values of the pixels in the
 * selected pen and the destination bitmap are combined. Following are the two operands used in these
 * operations.
 *
 * <table>
 * <caption>Raster-operation code meaning</caption>
 * <tr><th>Operand</th><th>Meaning</th></tr>
 * <tr><td>P</td><td>Selected pen</td></tr>
 * <tr><td>D</td><td>Destination bitmap</td></tr>
 * </table>
 *
 * Following are the Boolean operators used in these operations.
 * <table>
 * <caption>Boolean operator meaning</caption>
 * <tr><th>Operand</th><th>Meaning</th></tr>
 * <tr><td>a</td><td>Bitwise AND</td></tr>
 * <tr><td>n</td><td>Bitwise NOT (inverse)</td></tr>
 * <tr><td>o</td><td>Bitwise OR</td></tr>
 * <tr><td>x</td><td>Bitwise exclusive OR (XOR)</td></tr>
 * </table>
 *
 * 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 pen and the selected brush: DPo.
 *
 * 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 all possible outcomes resulting from the Boolean operation on two parameters
 * (in this case, the pen and destination values). For example, the operation indexes for the DPo and
 * DPan operations are shown in the following list.
 *
 * <table>
 * <caption>Raster-operation examples</caption>
 * <tr><th>P</th><th>D</th><th>DPo</th><th>DPan</th></tr>
 * <tr><td>0</td><td>0</td><td>0</td><td>1</td></tr>
 * <tr><td>0</td><td>1</td><td>1</td><td>1</td></tr>
 * <tr><td>1</td><td>0</td><td>1</td><td>1</td></tr>
 * <tr><td>1</td><td>1</td><td>1</td><td>0</td></tr>
 * </table>
