Pxl-Test( uses a different direction of the coordinate system from all the
rest of the graphics functions. (0,0) is located in the upper-left and
(94,62) is located in the lower-right of the screen. Also, the syntax of
Pxl-Test( is reversed: Pxl-Test(y,x) NOT Pxl-Test(x,y) as you might think.
I hope this solves your problem.
