This change surely was intentional, as Richard only did switch alpha
blending on, when he got it working. I haven't had a chance to see this,
as both MinGW and Cygwin are still broken for me.

There should be a bit more output from the compositeGState:... method,
could you please provide that as well?
If you don't need alpha blending, it should just be fine to turn it off
completely.
