Performance tests on big models did not indicate any performance penalty in using doubles over floats, so the move to doubles should mainly impact precision improvements for whole earth databases. Also made improvements to osgUtil::PlaneIntersector and osgSim::ElevationSlice classes
Notes ===== The support in Image.cpp is also not full functional and should be rewritten in the future to support inline images. Currently osg::Images are supported via the osgDB::Registry::read/writeImage methods and plugins. Robert Osfield, March 2001.
