      To adapt to a world where multiple different graphics APIs that are taking precedence on different platforms, Qt has to reduce the dependency on OpenGL and become more independent of the underlying graphics APIs. The way to do this is to abstract away the parts we need from the APIs and make it easy and convenient to adapt to new protocols. This is similar to what QPA was for the window system.
