Hi Peter, You could use osg::DrawPixels drawable, but... its slow compared to using a textured quad as modern hardware is all geared up for making textures polygons really fast, glDrawPixels being left long behind. So... my recommendation is to stick with the osghud style approach using a single fullscreen textured quad.
