For me, it is reading 1px as 0.1mil.

px hacks seem like a bad idea to me.. (IE.. should have no conversion to
actual length dimensions, except in the context of the render code). This
is probably more a "type safety" kind of issue, than a hard bug.

I'm not up to git HEAD yet with my branches (haven't rebased past the layer
changes yet), but I don't recall seeing anything in the log which was
relevant to this.
