Reposition Window

Why would you have to redo a fair bit?

Its just a simple switch at the beginning :-)

If fullscreen
   graphics ...
else
   create Window
   Create Canvas
   Set Focus on Canvas
   enable polled input
endif

After that point you can work on as you intend to do with graphics unless I missed something very important ...

And it allows you to reposition the window if in windowed mode :)
