Also, what if I have this box:
X:0,Y:0,W:100,H:500
And have the Horizontal set to True? The box is clearly vertical. What would th engine do, stack a vertical menu, then put an arrow at the top left/bottom right, and make the scrolling keys left/right instead of up/down? Or would it just ignore the horizontal? When you set it to horizontal does it ignore the height option, and just go with width?
