This demo demonstrates use of Raster Graphics, Dialog, and Mouse.

• You can drag the window around.
• You can close the window, press "Show Window" to show it again.
• Drag the shape to rotate it manually. If you are using IE8 or earlier version, be patient and move slow to see the effect (IE8 and earlier use a very slow API for graphics, VML). Try Firefox, Chrome, Safari, or IE9 for a much faster/butter-smooth experience.
