This aligns FFmpeg/libswscale destination image buffers and validates
the buffer-size, frame-fill, and swscale return paths before decoded
pixels are consumed.
The change prevents narrow high-bit-depth VP9/GBR inputs from writing
past OIIO's destination buffer during swscale conversion, and adds a
regression case for the width-1 high-bit-depth FFmpeg path.

This handles malformed GIF files whose logical canvas dimensions can
overflow legacy int-indexed canvas calculations.
The patch rejects oversized canvas dimensions before scanline/canvas
indexing and adds a regression test for the malformed oversized-canvas
case.

This treats non-positive tiff:RowsPerStrip metadata as absent before
using it to align generic scanline read/write chunks. That avoids
feeding invalid chunking metadata into round_to_multiple while
preserving normal positive RowsPerStrip behavior.
The patch adds regression coverage for an OpenEXR file carrying
RowsPerStrip=0 through iinfo --hash, iinfo --stats, and an oiiotool
conversion path.
