Swirl or Liquify tool create null pixel data at the bottom of the image.

When you use the liquify or swirl tool on the bottom of the image, some of the new pixels have the value rgb(0,0,0,0). It seems to be grabbing pixels from out of bounds of the image, but only for the bottom of the image, not the left, right, or top.

It also has this issue at the top, but seemingly it is much less noticeable. This is Kalvin's code, so I think they should probably look at this.

You can also color pick 0,0,0,0 pixels from the top and bottom. I think that is related.

This is a functional bug, as it related to our swirl and liquify FRs.
