Almost done with the refactor.  But there are a few errors from
incomplete refactoring remaining.
More work on cleaning up camera code
Still working on some bugs in image export, but progress has been made
Fixed painting and export image issues
Converted back to AWT GLCanvas, converting NEWT mouse events to AWT was
laggy for some reason
Renamings and deleted some old JOGL utility classes
Fixed more bugs with image export, almost ready for prime time
Added OutOfMemoryError check on JoglExportImageDialog.  Todo: figure out
bug with typing in new image size.
merged scene refactoring branch
Added code to properly set the max number of samples in BreakoutMainView
and JoglExportImageDialog.  This also fixes the bug where sometimes the
image was not loading the first time the export image dialog comes up.
