Scale up the image by an integer factor and using bilinear interpolation. This is fast and predictable and will invert DownRez without shifting the image any, so the pair can be used by the fast blur.

_validate() sets the output size to include the 1/2 of an unscaled pixel that will be filled outside the image.
