This is where I disagree. The goal of QtGui is to enable developers to write 
GUI applications easily and efficiently. Those applications may or may not use 
Qt Quick 2 and/or controls and many of them of course do so. However, a very 
large percentage also need to integrate with other things too.

I agree with Bjoern and Gunnar that making use of QOpenGLFunctions within Qt 
Quick 2 seems the better way to go. I still need to think my way through more 
of this yet and my brain is already suffering from the Friday Feeling.

I totally understand the desire to be able to select an OpenGL/ES2 
implementation at runtime for applications that are only using OpenGL 
indirectly via Qt Quick 2.

Have a good weekend,

Sean
