Summary: Overflow error when zooming to much

Initial Comment:
When you zoom in too much, you end up with a Overflow exception.
Just open a graph with zoom enabled. Drag a box from left to right, and the height as small as posible - repeat until error.

Zoom interaction was crashing when zooming in multiple times... Now
checking if the graphics extends before allowing the update

Handle the PlotSurface2D.PreRefresh event and check the worldmin /
worldmax / worldlength properties of x- and y-axes.

This is happening in LinePlot too. When I zoomin to the lowest level, this
is happening. I guess problem could be with Transform.
