[Feature Request]: Put a link functionality (and a chain icon button) between "Upscale by" and "Resize width to" and "Resize height to" sliders.

Is there an existing issue for this?

What would your feature do ?

It would put the current (calculated from width x "Resize by" and height x "Resize by") values in "Resize width to" and "Resize height to" bars respectively, and the numbers would stay after disabling the lock. It could be, for example, here.

Then, after deactivating the linking, the user would be able to change the "Upscale by" to 1, thus using only the calculated values. Is it a beneficial idea?

Proposed workflow

1. Enable "Hires. fix".
2. Press "Link" or similar checkbox near the "Upscale by" slider.
3. Watch the magic happen. :)
