>> Thanks @azvegint. If the `int`-based dimensions are coupled with `com.sun.javafx.geom.Rectangle` (and from the code, that's the only place they are used at), would you object to making `Dimension` an inner class of `Rectangle`? The `float`-based dimensions are used in other 2D shapes, so are more general purpose.
