Result = ClipSprite(#Sprite, x, y, Width, Height)
Add a clip zone to the specified sprite. For example, if a sprite is 100*100 (Width*Height) and
a clipping zone is added as x=10, y=10, Width=20, Height=20 then when the sprite is displayed, only the rectangular
area starting from x=10, y=10 with width=20 and height=20 will be displayed.
To remove the clipping of the #Sprite, use #PB_Default constant for 'x', 'y', 'Width' and 'Height'.
Note: On some older gfx cards the clipping with ClipSprite() doesn't work properly,
if the sprite is larger than the used screen.
