I recommend using Float or Double instead of Int for your point
coordinates.  You'll eliminate  the need to convert to Float/Double.  More
importantly, your whole model will then be resolution independent,
supporting continuous scaling, sub-pixel translation, rotation, etc.  See
http://conal.net/Pan for examples & papers.
