Added osgtexture3D demo, renamed osgtexture demo to osgtexture2D, and have

Browse Source 
added osgtexture1D demo which currently is simply copy of osgtexture2D. I
will be modifying it to do 1D texturing next.

Fixed a bug in osg::Texture3D relating to checking of existance of
texturing.

Merged some fixes to the pfb loader from Ulrich Hertlein.
