OpenGL Displays.

The MG_OGL displays are kinda broken. For instance, in the DX version, the graphics are scaled when the window is resized. In OpenGL that is not the case. This would be an easy fix by adding:

 protected override void OnResize(EventArgs e)

  GL.Ortho(0, yoursizehere.Width, yoursizehere.Height, 0, -1, 0);

To the default window class.
Also, when setting the window to fullscreen (graphics.ToggleFullscreen();) it only makes the window borderless, not fullscreen. This could be fixed by calling: WindowState = WindowState.Fullscreen;.

Anyway, great framework, I am currently using MonoGame for a project and really enjoying it!
Keep up the amazing work!
