#3436: Added the INTERLEAVE value to the IMAGE_STRUCTURE domain for ENVIDataset. Also fixed the overflow check.
#3462: Reviewed a fix to gdal_contour algorithm. Need to write a test script for further testing.
#3473: Caught a bug in GDALRasterizeLayers() that was revealed by a bug in the script tiff_write.py.
#3467: Applied a patch to fix a bug in OGRPolygon::PointOnSurface() and OGRPolygon::Centroid()
#3385: Applied a patch to fix problems caused by a call to unixODBC in some architectures.
