So it's not optimized to reject anything outside of the sub-
rectangles? This sentence really threw me off. In retrospect and I
can see that it simply means that it's doing a simple check up front
like below, but it's a rather poorly worded description as it
doesn't mention the sub-rectangles at all. Documentation fail. ;-)
I agree it's a long-winded way to say it's performing a basic
intersection check, but I think it's probably historic - the
subrectangles weren't available until 10.3 (I think, maybe it was
10.2?) so previous to that you only had the overall bounding box to go
on. The docs may not have been revised since then.
