Scale UI

[jellewie]

Make it so that everything within /Canvas/UI would scale.
Now only 1080P works, but when you go to 4K everything is too small. It needs to be relative to the Size if the UI

Note: The UI is going to be a custom size and position, so when you play on a 3 monitor setup, you could set the UI to just be the size of 1 monitor and on the middle monitor (At least that was the plan)
(start XY, and size XY)

I've changed 'Canvas Scaler' to 'Scale with Screen Size' and now everything scales (Which is fine)

We now only need the options as stated in #49
Or bugs need to appear from this option
