  1. Use bilinear filtering for resizing grayscale images (disabled by def… 

    …ault)

* Lanczos is a good default when resizing, however, it is suboptimal for masks as it can introduce ringing artifacts. So use bilinear in these situations.
* Bicubic is better than Lanczos here, but can introduce "pinching" on corners. Nearest would be optimal for binary masks, but much worse if there's any blurring.
* Adds a new toggle to the img2img settings, which is disabled by default, as it does affect the shape of masks compared to Lanczos.
