Backported upstream patch to fix buffer underflow crash in
TIFFReadRGBAImageOriented() when handling images with fewer raster
rows than requested. The patch adds verification logic to check
raster dimensions against image dimensions and adjusts accordingly.
Manual conflict resolution was required for libtiff 4.0.9
compatibility, replacing TIFFWarningExtR() with TIFFWarningExt()
to match the function signature available in this version.
