and deserialization for encoding and decoding bitmaps. Remove kForceFlattenBitmapPixels_Flag, which is no longer used. When an SkOrderedReadBuffer needs to read a bitmap, if it does not have an image decoder, use a dummy bitmap. In GM, add a tolerance option for color differences, used when testing picture serialization, so it can assume two images are the same even though PNG encoding/decoding may have resulted in small differences. Create dummy implementations for SkImageDecoder and SkImageEncoder functions in SkImageDecoder_empty so that a project that does not want to include the images project it can still build. Allow ports to build without images project. In Mac's image encoder, copy 4444 to 8888 before encoding. Add SkWriter32::reservePad, to provide a pointer to write non 4 byte aligned data, padded with zeroes. In bench_ and render_ pictures, pass decode function to SkPicture creation from a stream.
