Description Bernhard Beschow 2013-02-28 20:38:42 UTC

The top white circle of the coordinate grid looks distorted when the globe is
* in spherical projection
* focused on "Al Wakrah"
* almost wholy visible.

Reproducible: Always

Steps to Reproduce:
1. Make sure the coordinate grid is visible
2. Select spherical projection
3. Focus on "Al Wakrah"
4. Make the whole globe visible
Actual Results:  
The top white circle looks distorted where it should be covered by the globe.

Expected Results:  
The top white circle should be invisible where it is covered by the globe.

The problem is that the "globeHidesPoint" variable in AbstractProjectionPrivate::crossDateLine() doesn't cause the current QPolygonF to be split.
