    Description

      Forked from QTBUG-36091.

      We need to implement the proxy approach for dynamically loading either opengl32.dll or libegl.dll+libglesv2.dll on application startup. The llvmpipe-based sw renderer is not in scope here.

      This should eliminate the need for two separate build configurations (desktop vs. angle).

      WinRT is not affected, that continues to rely directly on Angle. Similarly, static Angle builds should still be possible.
