Correct and improve the rendering of QuickMapItems

Various MapItems were not rendered correctly, especially in corner cases.
This change ensures that MapItems are rendered correctly in the vast
majority of cases.

All MapItems are shown correctly if they wrap around the globe and
appear twice on the map.

Circles that span around the globe or are located near poles are shown
correclty and filled all the way to the border of the map.

Polygons are shown correctly including their holes.

The code was simplified and some artefacts of previous implementations
were removed.
