Currently if you request a 256 x 256 tile that exactly lines up with an actual tile you will actually end up downloading 3 extra tiles because of an off by one error being used to calculate the needed tiles

I don't believe the build failures are related to this pull request

ok the build is fixed and I believe was broken ever since you upgraded the location of spherical mercator.
