OpenSceneGraph/include/osgSim/LightPointNode
Robert Osfield 7aab621405 Added support for min pixel size, max pixel size and max visable distance to
osgSim::LightPointNode, the max pixel size from was originally in osg::LightPoint.

Added additional get/set methods to osg::LightPointNode.

Increased the compute pixel size by a ratio 1.41 (sqrtf(2)) to correlate the
computed size with the actual size seen on screen.
