That's the opposite of what I was expecting. I was expecting most places
to return null and South Korea to return four regions:
32.9890840,124.6055600,38.6930130,128.4960940
34.4646740,128.4960940,38.6930130,128.8476560
35.0277470,128.8476560,38.6930130,131.0531620
37.0277730,131.0531620,38.6930130,132.0034790
The South Korean government only permits their streetmap imagery to be
served from a server inside their country. So Google switches tileserver
when you zoom in within one of those rectangles. E.g. using
http://mt0.gmaptiles.co.kr/mt/v=kr1.9&hl=en&x=872&y=396&z=10
instead of
http://mt0.google.com/mt/v=ap.97&hl=en&x=872&y=396&z=10
I thought that GAppFeatures might be part of the system that controlled
the switch.
