Copperbox revision 2274.

I've re-implemented the affine transformations on Points and Vectors as simple functions rather than matrix / homogeneous coordinate operations.

This has good implications for the unit handling as it means Real and Floating are enough to compute transformations: the unit doesn't need to be cast to Double, which needs InterpretUnit. Thus it looks like the classes can be generalized back to what they were in 0.43.0 with the exception that scale should work with Double for the scaling factors and not the unit - u.
