The autorotate does not work

[tobiashill]

The code as well as the readme give the impression that autorotate has been properly implemented.
It does not seem so. It is easily verified in the demo application. The two test images comes out flipped.

Also this is a good resource for all versions Orientation in EXIF: https://github.com/recurser/exif-orientation-examples

No exif extraction and rotation needed anymore. As if (guessing) browsers of today (in the process where the image is being rendered on the canvas) is done so correctly rotated / mirrored.
