Request for rotate canvas, erase brush, sharpen slider for inpainting, please.

[WillKru2]

The ability to rotate the canvas in inpainting is needed for working with Reactor and other face swapping extensions as they have trouble replacing a face that is at a 90 degree angle or upside down. An erase brush is needed to easily be able to make holes in the mask for facial features that you don't wish to change like closed eyes, a nose piercing or teeth showing, etc. A sharpen slider would be useful for matching the sharpness of a swapped face with the rest of the photo.
