/**
 * This method is called on a destination SurfaceData to choose
 * the best SurfaceData from a source Image for an imaging
 * operation, with help from its SurfaceManager.
 * The method may determine that the default SurfaceData was
 * really the best choice in the first place, or it may decide
 * to use a cached surface.  Some general decisions about whether
 * acceleration is enabled are made by this method, but any
 * decision based on the type of the source image is made in
 * the makeProxyFor method below when it comes up with the
 * appropriate SurfaceDataProxy instance.
 * The parameters describe the type of imaging operation being performed.
 * <p>
 * If a blitProxyKey was supplied by the subclass then it is
 * used to potentially override the choice of source SurfaceData.
 * The outline of this process is:
 * <ol>
 * <li> Image pipeline asks destSD to find an appropriate
 *      srcSD for a given source Image object.
 * <li> destSD gets the SurfaceManager of the source Image
 *      and first retrieves the default SD from it using
 *      getPrimarySurfaceData()
 * <li> destSD uses its "blit proxy key" (if set) to look for
 *      some cached data stored in the source SurfaceManager
 * <li> If the cached data is null then makeProxyFor() is used
 *      to create some cached data which is stored back in the
 *      source SurfaceManager under the same key for future uses.
 * <li> The cached data will be a SurfaceDataProxy object.
 * <li> The SurfaceDataProxy object is then consulted to
 *      return a replacement SurfaceData object (typically
 *      a cached copy if appropriate, or the original if not).
