Outpaint Pixaroma

Pads an image with a solid colour so an outpainting model can fill the new area in, then optionally scales the result down to a megapixel limit and reports the final size. Mid grey is the default fill. Any colour works, but a strongly coloured fill can tint the whole generated image, because a model trained to replace it learns the colour as well as the shape. Grey is neutral, so it has no hue to bleed. To ratio grows the image to a target shape and the anchor decides which side the new space appears on. By side lets you set an exact number of pixels per edge. The megapixel limit is optional: with it off the image keeps its padded size. The width and height outputs report the FINAL size, so they can feed an empty latent directly.
