Created Unassigned: zoom in throws a StackOverflowException [63625]

When zooming in to an extent of less then 1e-7 in OnViewExtentsChanged of DotSpatial.Controls.Map, the ViewExtender will be caught in a infinite loop and will eventually throw a StockOverflowException.

This was achieved by scrolling in a couple of times on a shape.
Attached are the ViewExtents' values during the infinite loop.

Please have a look at this.
Cheers
