Different coordinate system on different iOS devices

[bpawel10]

Hi,

on newer iPhones, for example iPhone 5S or 6S, normal touch coordinates work fine. However, when I test it on my iPhone 4, touch coordinates are very strange and I need to change it to use:

screenX = screenY;
screenY = Gdx.graphics.getHeight()-screenX;

and then it works.

Would prefer not to track this in multiple places.
