Hi,
I'm using osg::Operation to perform async tasks and
osg::GraphicsOperations added via setRealizeOperation to perform
on-realize per context tasks.
What is the correct usage of osg::GraphicsOperations if I want it to be
performed once per frame and context? Let's say at the end of the draw.
My intention is to use the NVX_gpu_memory_info[1] to keep track of
memory use and eviction, and since it needs a valid context to operate
correctly I thought the graphicsOperation would be the way to go.
