contents distorted when the window is resized

[blueeyedlion]

When I resize my window, its contents are horribly distorted.  How do I get the contents to remain unchanged and show a bit more space at the bottom right?

Catch the Resized event and adjust the window's view to the new size (by default it always keeps the original size, thus enlarging the contents instead of showing a bigger area).
