Add ANGLE as a 3rdparty library to Qt.
ANGLE is a component that implements the OpenGL ES 2.0 API on top of DirectX 9. See the following for more info: http://code.google.com/p/angleproject/ ANGLE is now the default configuration on Windows. If you want to use desktop OpenGL, you should build Qt with the following configure options: -opengl desktop To configure Qt to use another OpenGL ES 2 implementation, you should use: -opengl es2 -no-angle Task-number: QTBUG-24207 Change-Id: Iefcbeaa37ed920f431729749ab8333b248fe5134 Reviewed-by: Friedemann Kleint <Friedemann.Kleint@digia.com>
