Get rid of deprecated functionality in QtOpenGL.
We will in any case not be able to support this in Qt 5, so best to just remove it to not give any false impressions. Change-Id: Ib52e86007b9e6483bd973f13502b078792a9fa40 Reviewed-by: Sean Harmer <sean.harmer@kdab.com> Reviewed-by: Lars Knoll <lars.knoll@digia.com>
