However, the resulting map is coming out scaled up by 125%.  The only way I've discover to fix this is by scaling the bbox in the grid definition down by 125%, but that means that the last 25% of the globe is chopped off.  Has anyone else encountered this kind of problem?  Here's my conf.yaml file:

You need to configure the exact BBOX, tile_size and resolutions of your source WMTS service (see capabilities). You might get images back with different settings, but they won't align.
