OpenFileGDB rendering with SetSpatialFilterRect

Bug description

When reading from the cdfadmin13_1_unit layer of cdfadmin13_1.gdb with OpenFileGDB driver and setting a SetSpatialFilterRect from Mapnik I'm seeing not all shapes returned. The incorrect.png demostrates this. It should be a solid red color, but instead some polygons are missing and the shapefile underneath renders green and shows through.

Data from: http://frap.cdf.ca.gov/data/statewide/cdfadmin13_1.zip downloaded from http://frap.cdf.ca.gov/data/frapgisdata-sw-cdfadmin13_1_download.php

I found:

  • disabling SetSpatialFilterRect works around the problem (produces no_filter.png below)
