Aliased drawing has so far not been perfectly pixel aligned, resulting in
less than stellar output in some instances. Although a little hacky,
adding 0.5 to all coordinates when in aliased mode fixes things up nicely.
There doesn't appear to be a better way to get d2d to cooperate as we
would like it to.
