What should this feature add?
When using the Upscaler, selecting the right Upscale Model can be tricky since they all have issues of their own, such as artifacting, discoloration, etc. Often times, that part of the upscaling process is less important than the prompt and SDXL model settings.
Bicubic upscaling is a traditional (pre-AI) way of upscaling while simply smoothing the pixel aliasing, without adding artifacts or changing colors or other aspects of the image. Such an option could make upscaling certain kinds of images much less challenging.
