[Ves] Shading

[Chris Vaught]

The attached image shows a very simply plate with a hole in the center.
 This is a simple stl file with no contour data.  The stl file is also
attached.  The resulting shading appears to be messed up.  Any thoughts on
why this is and how to fix it?  Also, I am working with the example ios
application.  How do you change the background color?  I changed the
background color of the GLView in MainWindow.xib and that did not work.

Thanks
Chris
