  - The following 3 steps are repeated for every viewport in the splitscreen
    - Set the viewport to the area you wish
    - Activate the camera which should be "linked" with the viewport
    - Render all objects

  - If you have a GUI:
    - Set the viewport the whole screen
    - Display the GUI
  - End scene

Sounds a little complicated, but you'll see it isn't:

		- Y-coordinate of the corner left top
		- X-coordinate of the corner right bottom

		- 1st viewport: 0,0,ResX/2,ResY
		- 2nd viewport: ResX/2,0,ResX,ResY
