> * This is a very simple test of the 4 repeat modes made available as
> * of version 0.10 of the X render extension. The 4 repeat modes are
> * tested with a simple 2x2 source being drawn with an offset to an
> * 8x8 destination. No other pattern transformation, (eg. rotation or
> * scale), is tested here.
