-/* The raster and associated properties of a mapped screen region.
- * The compositing capabilities of backends are often insufficient.
- * The backend may not support alpha blending, or may not support some
- * other special compositing rule. This means that compositing must
- * sometimes be done within the rendering pipeline. The general
- * compositing operation consists of combining new color and alpha
- * values with existing color values on the drawing surface, to find
- * the new color values for the drawing surface. The way the values
- * are combined, determines what kind of compositing operation that is
- * performed. The default compositing operation is alpha compositing.
- *
- * <p>In order to perform alpha compositing and other compositing
- * operations, we need access to the color values of the imagery that
- * has already been drawn on the drawing surface. The
- * DirectRasterGraphics interface must therefore contain methods that
- * makes it possible to gain access to the pixel values of the drawing
- * surface. The methods are modeled after the POSIX mmap() and
- * munmap() functions. But, instead of mapping and unmapping portions
- * of data from a file descriptor to memory, the methods in
- * DirectRasterGraphics maps and unmaps portions of the drawing
- * surface to data arrays within writable raster objects. A call to
- * mapRaster() will return a writable raster object, encapsulating the
- * image data of the drawing surface in the requested domain. The data
- * encapsulated by this raster object can be modified using the
- * WritableRaster API, or the data buffers can be retrieved from the
- * raster, so that the data arrays can be manipulated directly. When
- * the raster image has been modified as desired, the data can be
- * resynchronized with the drawing surface by calling mapRaster().
- *
- * <p>As with mmap() and munmap() the methods may work by direct
- * manipulation of shared memory, (i.e. the raster object directly
- * wraps the actual image data of the drawing surface), or may make a
- * private copy that is resynched when the raster is unmapped. The
- * backend may choose to implement either mechanism, and the pipeline
- * code should not care what mechanism is actually used. This design
- * allows us to make full use of speedups such as X shared memory
- * extentions when available.
