[KPhotoAlbum] mapview-patch

[Reimar Imhof]

Hi Johannes,

I ran into a new problem I've got for some image clusters (since kphotoalbum 
7.0):

When clicking a "problem" image cluster I get less images then the cluster 
includes. I get all images if I don't click the cluster but pull a selection 
around the cluster.
It seems that m_boundingRegion does not include all images for the "problem 
clusters".
I've tried to put a delta (0.0001) to the cluster in 
GeoCluster>>boundingRegion() :
        ret_region.setNorth(m_boundingRegion.north()+delta);
        ret_region(m_boundingRegion.south()-delta);
        ret_region.setEast(m_boundingRegion.east()+delta);
        ret_region.setWest(m_boundingRegion.west()-delta);

I could solve the problem for some clusters that way but not for all of them.
And I got funny effects: The size of the cluster (shown an the map) changed 
unexpectedly when changing the map resolution. 

Could you have a look?

Thanks,
Reimar
