Summary	05993: prescale option is now limited to 3
Description	From some time prescale option is limited to only 3 at max. Previously it worked to 4. In newwideo.txt is mentioned as working from 1 to 8.
Steps To Reproduce
Additional Information	If we prescale let's say 256x224 then for filtering we get prescale 2 (512x448), prescale 3 (768x672), prescale 4 (1024x896) prescale 5 (1280x1120). Those ranges are acceptable for most of modern LCD monitors.

No.11893 haynor666 Tester Jul 24, 2015, 09:33	I noticed some time ago that using prescale with filter causes to position/stretch a bit incorrectly but limiting this option will just in my opinion hide the problem.
