[MetaCRS] Differences between results for 7-param transform

[Jan Hartmann]

The only suggestion I could make is to reverse the rotation parameters 
4-6. In some countries the rotation is clockwise, in others 
anti-clockwarse. So try changine plus into min and min into plus in 
these three parameters.
