Make QEglContext API a little more flexible
Allow higher layers in QtOpenGL and QtOpenVG to set the EGLConfig and EGLContext manually if they have some other way to determine what the values should be (e.g. constructing a special config for a specific platform). Also add a QEglProperties argument to createContext() to allow fine-tuning of the context parameters. Reviewed-by: Sarah Smith
