TILDataset doesn't use overviews

Reported by: bishop Owned by: warmerdam
Priority: normal Milestone: 1.10.0
Component: default Version: svn-trunk
Severity: normal Keywords: TILDataset GDALDefaultOverviews Overview
Cc: antonio

Description

The TILDataset does not use overviews, always choosing to read the entire source data. It may be the bug of GDALDefaultOverviews because BuildOverviews? -> GetOverview?() but BuildOverviewsSubDataset? -> ? In ReadIO function the TILDataset checks overview manager for number of overviews but it always return 0.
