+//
+// Given a blob that represents an encoded image, decode the image, crop it,
+// rotate it, resize it, encode it again and pass the encoded blob to the
+// callback.
+//
+// If the image includes EXIF orientation information, it will be
+// rotated and/or mirrored so that the proper side is up and EXIF
+// orientation information will not be needed in the output blob. The
+// blob will not include any EXIF data.
+//
+// The cropRegion argument is optional. If specfied, it should be an
+// object with left, top, width and height properties that specify the
+// region of interest in the image. These coordinates should be
+// specified as if the image has already been rotated and mirrored. If
+// this argument is not specified, then no cropping is done and the
+// entire image is returned.
+//
+// The outputSize argument specifies the desired size of the output
+// image.  If not specified, then the image is returned full-size. If
+// this argument is specified, then it should be an object with width
+// and height properties or a single number.  If outputSize is an
+// object, then the returned image will have the specified size or
+// smaller. If the aspect ratio of the output size does not match the
+// aspect ratio of the original image or of the crop region, then the
+// largest area of the input region that fits the output size without
+// letterboxing will be used. If the output size is larger than the
+// crop region, then the output size is reduced to match the crop
+// region.
+//
+// If outputSize is a number, then the #-moz-samplesize media fragment
+// will be used, if necessary, to ensure that the input image is
+// decoded at the specified size or smaller. Note that this media
+// fragment gives only coarse control over image size, so passing a
+// number for this argument can result in the image being decoded at a
+// size substantially smaller than the specified value. If outputSize
+// is a number and a crop region is specified, the image may be
+// downsampled and then cropped, further reducing the size of the
+// resulting image.
+//
+// The outputType argument specifies the type of the output
+// image. Legal values are "image/jpeg", "image/jpeg+exif" and
+// "image/png". If not specified, and if the input image does not need
+// to be cropped resized or rotated, then it will be returned
+// unchanged regardless of the type. If no output type is specified
+// and a new blob needs to be created then "image/jpeg" will be
+// used. If a type is explicitly specified, and does not match the
+// type of the input image, then a new blob will be created even if no
+// other changes to the image are necessary. "image/jpeg+exif" is what
+// you want if you need to have the Exif in the updated copy.
+//
+// The optional metadata argument provides a way to pass in image size and
+// rotation metadata if you already have it. If this argument is omitted
+// or null, getImageSize() will be used to compute the metadata. But if you
+// have already called getImageSize() on the blob, you can provide the
+// metadata you have and avoid having to reparse the blob.
+//
+// The callback argument should be a function that expects two arguments.
+// If the image is successfully processed, the first argument will be null
+// and the second will be a blob.  If there was an error, the first argument
+// will be an error message and the second argument will be undefined.
+//
+// If no cropRegion and no outputSize are specified, if the type of the
+// input blob matches the requested outputType, and if the image does not
