When the drawn rectangle is on a single screen, the output image uses the screen native resolution.
When the drawn rectangle is on screens with multiple scale factor, the output image is upscaled to correspond to the screen with the hightest scale factor to keep the image undistorted.

Adds also a "scaled" full screen mode, to capture screens content downscaled to screens virtualsize allowing for undistorted content albeit loosing details.

Requires Plasma 5.19.80+
