Thumbnails for Kindle Scribe are resized and look weird

[Maria Paula]

As it was fixed in the release 7.12.0, the resolution is good now, and the thumbnail does not look pixelated. But now, the thumbnails are being shown the wrong size, they look kind of squared and not rectangular.

There is nothing I can do about how the kindle chooses to present
thumbnails. THe thumbnails are sent with whatever aspect ratio the
actual cover images have.

I did modify the covers and it is supposed to be 1000 x 1500 pixels. But when sending it to the Scribe it's making them square. That's why I opened the bug. It's still happening.

Fixed in branch master. The fix will be in the next release. calibre is usually released every alternate Friday.
