read_native_scanline() and read_native_tile() called readimg_scanlines() and readimg_tiles() but ignored their return values, so a failed or short decode was copied out of m_buf as if it had succeeded. Check the returns and fail the read instead. Assisted-by: GitHub Copilot / Claude Opus 4.8 Signed-off-by: Larry Gritz <lg@larrygritz.com>
