Zoom change

[SpicaThor]

When changing zoom it's changed with anchor point in the left top angle of frame. I don't know if it's done accidentially, but for me it seems more logical, that the map should zoom near it's center. It can be done with one change in one line of code. The RMMapContents.m file. The -(void) setMetersPerPixel: (float) newMPP method. Line number 826 (at least in the code I have). Instead of CGPoint pivot = CGPointZero; should be CGPoint pivot = CGPointMake(layer.frame.size.width/2.0, layer.frame.size.height/2.0);
