test case

See attached test case -- this test uses a jpeg that contains an exif header indicating that the image should be rotated 90 degrees.  When displayed via an <img> tag the image shows up at the correct orientation, but when displayed by decoding with createImageBitmap() and then drawing the resulting image to a canvas, the image is not correctly rotated.
Although not covered by the test case, if an ImageBitmap is created with an ImageElement as the source, the orientation is handled correctly.
