Feature suggestion: ability to scroll pictures

[banditByte]

First, thank you for the excellent library.
However, I noticed that the image drag mode is only activated at high magnification. Dragging an image isn't very convenient, and when it's the only way to see the details of an image with too big difference in aspect ratio, it becomes completely inconvenient. Therefore, I would suggest to give the possibility to scroll the image with the arrows. Yes, I know that zoom is attached to them, but you can track "Control" or "Alt" keypressing or something.

Yes! I'm missing that feature also :)
