BoundingBox behavior around 180th merdian

[niklas88]

The BoundingBox should probably behave like this around the 180th meridian. Instead once the right border goes across 180° the left border also jumps to -180°. Moving further eastwards the BoundingBox expands again. I'm also a bit confused about the min/max format here, this wiki makes it sound like storing left, right, top and bottom is the same but around the 180th merdian the right might be smaller than the left.

I didn't really have time to look at this in the last two weeks. This actually a known issure (to me at least). As for the min/max format, I would suggest to have the right border coordinate to be smaller than the left one in this special case to distinguish it from a bounding box that wraps around nearly the complete globe from e.g. -178° to +178°.
