Backwards compatibility. In the past, we didn't *have* projection
objects: they're new in 2.6.

displayProjection is new in 2.6, so we went with the 'new way' of doing
things *only*: the Map will atually convert the string to a Projection
object latre on if you pass a string (which is why we have
getProjection(), and getProjectionObject() -- in 3.0, getProjection()
will start just returning the object, and we'll drop
getProjectionObject.) 

So: "historical reasons", but you shouldn't have to worry about it: if
you prefer, you can always use objects.
