#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()
