From Brad Colbert/Robert Osfield: added s/getSourceFormat and s/getSourceType to osg::Texture

Browse Source 
along with support for this Texture1D, 2D, 3D, TextureCubeMap and TextureRectangle.  The
new SourceFormat and SourceType parameters are only used when no osg::Image is assigned to
an osg::Texture, and main use is for render to texture effects.

Added support for --hdr option in osgprerender, which utilises the new Texture::setSourceFormat/Type() methods.
