* 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).
