You're requesting a tile that is 180 degrees wide and 90 degrees high. Since
your height/width are square, it seems like this isn't what you want to do.

Note that this URL does not return the requested bounding box -- you requested
the southwest portion of the globe, but it gave you the entire western
hemisphere.
