as OpenSG windows are just wrappers around the OpenGL parts you have
to use the specific functions of your window system/toolkit to change
the size of the window. E.g. if you are using glut either use/change
glutInitWindowSize to the size you want or use glutReshapeWindow to
achieve the same after the windows creation.

actually inside this function should be a call to window->setSize so
that OpenSG is told that the window size changed (we don't query for
these changes).

easiest is to change the code that creates your window toolkit window
to use the size you want. E.g. for glut use
glutInitWindowSize(800, 800);
before you call glutCreateWindow.
