Description

SetStatistics does not work for TIFF files.

Normally I open up a dataset and call ComputeStatistics() and the statistics get saved in the PAM file. This does not work for TIFF files though.

I'm attaching a patch that enables to use PAM with GeoTIFF. A few tests show that it doesn't seem to break things. However, I'm a bit shy about commiting it. I think it should also take into account the PROFILE of the TIFF file, in addition to the access status (see #1173).

Was implemented indirectly in 1.6.0 through better PAM support in the TIFF driver. See #2448 for the related commits.

I've also jsut added an explicit test for statistics storing and retrieval in r17437.
