[osg-users] BindImageTexture Crash

[Julien Valentin]

The bufferobject is null because of the design used for unRefImageDataAfterApply feature
Texture owns textureobjects in order to deref bufferdata

What I propose/ask to Robert is to release only data of the Image data keeping the chain Texture->BufferData(Image)->BufferObject(a new classTextureObject)->GraphicObject intact
