SetROP2 sets the binary raster operation which affects how the current brush
and pen combine with the existing window contents when they draw to it, this
is equivalent to the GC functions in X, heres an equivalence table and info
where src is the brush or pen, and dest is where the pen or brush is being
applied, R2_COPYPEN is the intuitive default.
