here are the 2 things I want to achieve:
1. I need to get the state object so I can access the frame captured by the camera
2. I do not want QCAR to render the background for me
the problem is, the state object is returned by this line of code:
State state = QCAR::Renderer::getInstance.begin();
which also tells QCAR to start rendering the background,
is there any way to get the state object without rendering the background?
