[osg-users] BindImageTexture Crash

[Julien Valentin]

https://github.com/openscenegraph/OpenSceneGraph/pull/465

Here's what I'm thinking of....sorry for the huge commit
ChangeLog (in absence of commit history)

introduce a TextureGraphicObject ( buffered_object PCTOs -arg why can't I rename Texture::TextureObject to Texture::GLTextureObject, TextureGraphicObject is a so ugly name?!! - )
inject a base class for PerContextGraphicObject (base of BufferObject, TextureGraphicObject (bufferedPCTOs), ProgramsObject ..)[/list]
deprecate Image less Texture by adding an Image with NULL data (may require further data==0 tests to ensure retrocomp) and make unrefimageafterapply just deallocate Image
remove buffered_object from Texture to use the TextureGraphicObject of its Image[/list]

I'll try to clean the PR if community is everyone happy with it
