Low resolution/pixelize effect on unity with urp render scaling (experiment)

Описание

Experiment on low resolution effect on unity urp, wouldn't really advice on using it because it modifies urp files and i haven't really looked into that. Benefit with this method is that it increases performance, compared to for example the method where you use a render feature to pixelize the screen after it has already been rendered or the method where you use render texture on a raw image which requires you to use a ui image for it and it breaks stuff like click on screen space camera buttons and similar stuff. The render scale calculation progress isn't perfect since i didn't spend too much time on it, and for example there may be a few unregular resolutions where the intended pixel height is one lower that intended, but i didn't find it a big issue.
