* Fixes for DPI scaling.  Mouse and select events now deliver GL surface coordinate values instead of the AWT screen coordinates.  Added Windows JOGL jar files that include https://github.com/sgothel/jogl/pull/110 and https://github.com/sgothel/jogl/pull/112.  Noticed that some null pointer exceptions occurred during KMLViewer startup; added null pointer checks.
