0N/A * This file contains macro definitions for the Encoding category of
0N/A * the macros used by the generic scaleloop function.
0N/A *
0N/A * This implementation can encode the color information into the
0N/A * output pixels directly by using shift and scale amounts to
0N/A * specify which bits of the output pixel should contain the red,
0N/A * green, and blue components. The scale factors are only needed
0N/A * if some of the color components in the output pixels hold less
0N/A * than 8-bits of information.
0N/A *
0N/A * This file can be used to provide the default implementation of the
0N/A * Encoding macros for direct pixel type displays with any size up to
0N/A * 8-bits of color information per component.
