JDK-8101141 - Image Ops
Description
In order to finish and vet the APIs for the RT-17409 ImageOps, the code that handles the methods on the new PixelReader and PixelWriter objects for both Image objects and Canvas objects was written using basic conversion loops that operate with a method call or 2 per pixel.  We need to replace those prototype implementations with optimized copy/convert loops that work on a buffer at a time.
