Time for action - positioning and scaling the clock

The pie clock is pretty neat, but it's sadly stuck to the top-left corner of the screen. It would be great if we could make it any size we wanted, and if we could move it anywhere on the screen.

We're not far off from that goal. Follow these steps to get a dynamically positioned and scaled pie clock:

1. Create these variables at the top of the OnGUI function:

   var pieClockX:int = 100;
   var pieClockY:int = 50;
   var pieClockW:int = 64; // clock width
   var pieClockH:int = 64; // clock height
   var pieClockHalfW:int = pieClockW * 0.5; // half the clock width
   var pieClockHalfH:int = pieClockH * 0.5; // half the clock height
   

   In this example, 100 and 50 are the X and Y values where I'd like the pie clock to appear ...
