Comment:

 The problem is the scaling code. If you try to scale a 2x20 image with the
 ratio 0.25, you will get a 0.5x5 image. We use integers, so we get a 0x5
 image in this example. We should round up image sizes with 0px. I fixed an
 equivalent bug in the preview generation of the image editor.

 Maybe we should reorganize the code to avoid the redundant scaling code.
