[osg-users] image is not being freed

[Bruno Oliveira]

OK, I understand that. I do that because I own the data pointer I'm
sending, and I am totally sure I am freeing it. However, some other copy
remains anywhere, and I don't have access to it.

If I delete the osg::Group where I am attaching images and re-add the same
imgaes, no more memory is allocated, so it is using the same buffers
somehow, but I can't force it to free the memory when I want to
