Sort files with drag and drop, scroll automatically

[BugFix]

Hi folks, unfortunately, automatic scrolling only works to a very limited extent or slowly when you grab an image and drag it to the top or bottom of the screen. Actually, it would be reasonable to display the next row immediately or at least scroll continuously. In other apps, you can even control the speed depending on how far you move the cursor across the edge of the viewport—the further you move it, the faster it goes. Unfortunately, this is not possible in XN.
