title: Wpf Viewport Coordinates
body: <p>Hey guys, Im working with wpf 3d, im currently writing a program that will create 3d tiles across the screen left to right, But i need to know what my bounds are on the X, Y i.e (-x-0) (0-x+) so I know when to start another row of tiles. My initial thoughts are trying to figure out a complex algorithm to go from pixels to screen coordinates, however it seems like there should be an easier way.</p>
