Might as well make these explicit so the cost is apparent.

This is the current upstream so let's make use of it to get the latest
in features and fixes.

It was unused and added complexity and bugs to the code. So let's
remove it rather than trying to clean up a function no one needed.

We already have an assignment operator, so no need for this method.

We've stolen the Xregion code from libX11, so let's keep the same
header naming so that it is easier to keep things in sync.
