Consider tilesize when calculating the grid #45

This never worked before. The calculation for sizes other than 1 did use the right center point for the static image.

The patch fixes that and also adjusts the test for it.

The code is currently used in a different fork that's deployed on the servers used here:

@2x zooms the stitched tiles.
