| Represents a Rectangle in Scratch.
|
| We can't use java.awt.Rectangle (for example) because Scratch rectangles can
| have floating point or integer limits, so hence we must store all measurements
| using the a class that can represent all of those.  Number would do it, but we also
| need to perform calculations so BigDecimal seems like a good alternative (plus, Scratch
| does support arbitrary precision integers).
