Thanks for taking a look at this and making comments.

Right, as a placeholder for coordinates that don't need to be
translated.

It will be for OpenMap 5.0, when the projection libraries change to
use Point2D. For OpenMap 4.6.4, I didn't want to change the UTMPoint
method signatures that do the conversion.

I'm still ironing out these kind of differences, thanks for pointing
this out specifically, though.

That's another thing I really liked about your implementation.
I know it's frustrating waiting for these things to get checked into
the code base, but I'm doing my best.
