Thanks. I did indeed see unsigned 32-bit values when using `@show`. ``` julia> using Winston julia> plot(0:01:1,sin((0:0.01:1)*4)) drawable = 185896600 hdc = Ptr{Void} @0x01010b3a drawable = drawable = 185896600 hdc...

Thinking aloud here. It seems like julia interprets the `hdc` is a pointer, so maybe `hdc` should be a pointer type...
