Growing an Extent is very common - we do this all the time in the Rapid code.
(Imagine code that loops over 1000 points to determine their bounding box).
In most cases, we modify the Extent's .min and .max directly for performance, rather than using the Extent.extend call. This is because Extent.extend(other) is written in an immutable style, so it returns a new Extent rather than just modifying the existing Extent in-place.
I'm going to change it so there are 2 functions:
Extent.extend(other) - immutable, returns a new Extent (same as before)
Extent.extendSelf(other) - mutable, modifies min and max in self (much more performant)
