Copy anchor points from Face Mask Texture to Opacity Texture

(Yes I know this is already part of another feature request, but that feature request combines it with some other things, and so I'd like to make a separate request.)

The Face Mask Texture interface allows you to automatically align the anchor points to the face in the image. This feature works great! However, it is then a HUGE hassle to try to try to re-create that setup in the Opacity Texture screen. I'd like a button in the Opacity Texture screen that allows you to "copy anchor points from Mask Texture" (and maybe also an analogous one in the Mask Texture screen, "copy anchor points from Opacity Texture).

It would be the icing on the cake if this button only applied the changes to the currently-selected anchor points, and a slider popped up to scale the degree to which the points are made to conform.
