Fixes #1574

When dealing with GeoTiffs that use ModelTiepointTag and ModelPixelScaleTag to define their coordinate transform, one must take into account whether the raster is considered PixelIsPoint. If this is the case, the tie point references the center of the cell, and the extent needs to be adjusted.

This approach is taken by GDAL, see here:
