From Kristofer, "The osgSim::ScalarBar has a problem in that if the scalarbar has a color in one end that co-incides with the background color, one cannot see where the scalarbar ends. With this patch, we add a line around the perimiter of the bar to mark it.

Secondly, we thought the text-annotation missed ticks that mark out precisely where on the bar the texts relate to, so we added that as well."
