Robert Osfield 31a947fda6 From Terry Welsh, "Okay, here are the mods I wrote for drawing a filled bounding box ... behind osgText::Text. I made it so the box would get drawn using whichever BackdropImplementation was selected. However, I did not implement STENCIL_BUFFER. In that case it defaults to drawing the bounding box using POLYGON_OFFSET instead. Also made it so the BOUNDINGBOX and FILLEDBOUNDINGBOX are drawn with a settable color and margin size. While I was at it I tightened up the values applied with DEPTH_RANGE and POLYGON_OFFSET, not just for drawing the bounding box but also for drawing backdrop text (these values must be coupled since the bounding box has to be drawn deeper in Z than the backdrop text). The values in use before seemed like overkill and I was seeing some z-clipping with my background scenery in the case of DEPTH_RANGE. If there was a good reason for the large values please let me know...."		2009-07-24 14:59:51 +00:00
