If the flag is set to true, we use in the DumpReplayer the default
MultiLayerModel. In case the user uses another model, one must asks the
user's model for debug purpose.
The dump files were updated to add the atmospheric refraction flag in
the direct loc and inverse loc lines.

This reverts commit b61d7ead.

This helps caller to set fix the min/max lines as we can provide
information about where the point is expected.
