ESRGAN_4x vs 4x-UltraSharp during hires fix at different denoising and upscale levels

Unfortunately, Automatic's X/Y/Z doesn't allow you to change the Upscale By value.

These charts show the differences between the two upscalers at different denoising levels during a hires fix.

The charts themselves are at different Upscale By levels, with the lowest being 1.25, and the highest being 4x. Expect to see more liberty taken by the upscaler at both higher denoising and Upscale By levels.

In order, the posts are the original 144x256 reference without upscaling via hires fix, followed by the 1.25x, 1.5x, 2x, 3x, and 4x upscale grids.
