Map tiles are not loaded if rotating the Qml Map component with angles other than 0, 90, 180, and 270 degrees and with clipping enabled.

Steps to reproduce:
1.) Open the mapviewer example shipped with the Qt Location plugin.
2.) Open the MapComponent.qml file and add:
<code>
rotation: 45
clip: true
</code>

The example will show markers but not the map tiles. When clipping is set to "clip: false" or the rotation angle is 0, 90, 180, or 270° then the tiles are loaded.
