Simon, as a side-note I have also bug 57261 for that migration. We need to modify symbol resolver to be on intelligent before doing that.

On Desktop OpenGL we always will need a symbol resolver to get those symbols that are not readily available in standard OpenGL header files. Note that Qt does similar things itself in painting subsystem.

I looked at the OpenGLShims implementation and it is in fact a symbol resolver. Code is direct derivative * of code in GraphicsContext3DQt but it is more limited. Symbols resolved are taken from global variable. Symbols returned by getProcAddress are context dependent. Therefore stable implementation cannot be based on a global variable.

* Can be seen by reading the code and from having a Tieto copyright.
