[osg-users] Allocating osg::image from my own data buffer

HI Bruno,

Simply clone the image i.e.

  osg::ref_ptr<osg::Image> iimag_copy = osg::clone(img);

The osg::Image will copy the internal image data without attempting to
share it, and will own it's own local copy of the data and delete it
automatically when img_copy is deleted (ref count goes to 0.)
