The implementation was not "real" code yet I was just playing there.
I have it implemented now and fixed that.
And yes thats correct it may run in out-of video memory.
Thats up to the application they can try to buffer up in video and if
it fails choose to buffer in main memory or not buffer.
There is nothing wrong with using up the vram if you want to.
