[Development] The Dynamic OpenGL on Windows Change

[Agocs Laszlo]

Hi Sean,

It is most likely better to postpone this whole feature, especially since it is not really user visible anyhow, and instead try mitigating the pain using some less intrusive methods for the time being, agreed. I am currently preparing a revert commit.

As for the role of qtbase and QtGui, I am afraid we will continue to disagree but perhaps that's fine. One cannot agree on everything. :)

Best regards,
Laszlo

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
