Touchpad-style cursor

[ghost]

First off, very impressed with the OpenMW port, I attempted it myself but got stuck on ESM read errors.

Now on to my suggestion, for a game with small buttons like Morrowind a direct touch-to-click style input for the touchscreen doesn't really work well. Instead a touchpad-style where you move the cursor by swiping your finger across the screen works much better.

A good example is the OpenRCT2 port: https://gbatemp.net/threads/release-openrct2-rollercoaster-tycoon-2-for-switch.537952/

I'm going to switch my Theme Hospital port to this input style as well. I'll submit a PR for OpenMW afterwards as well.
