Bugs

- hover works on tiles that are not in the viewport
- hover has to be cleared on rotation (same behaviour as selection before fix)

Next up

- move viewport across map (controls: NE, SW, SE etc)
- refactor select/hover effects to be rendered after the terrain to avoid occlusion
- illustrate current world viewport cut out on map viewport
