This commit and, by extension, PR attempts to update `stb` in the most straightforward way possible as well as include fixes from main repo's unmerged PRs for cases rearing their ugly heads during everyday usage: - stb#1299: stb_rect_pack: Make rect_height_compare a stable sort - stb#1402: stb_image: Fix "unused invalid_chunk" with STBI_FAILURE_USERMSG - stb#1404: stb_image: Fix gif two_back memory address - stb#1420: stb_image: Improve error reporting if file operations fail within *_from_file functions - stb#1445: stb_vorbis: Few static analyzers fixes - stb#1487: stb_vorbis: Fix residue classdata bounding for f->temp_memory_required - stb#1490: stb_vorbis: Fix broken clamp in codebook_decode_deinterleave_repeat - stb#1496: stb_image: Fix pnm only build - stb#1497: stb_image: Fix memory leaks if stbi__convert failed - stb#1498: stb_vorbis: Fix memory leaks in stb_vorbis - stb#1499: stb_vorbis: Minor change to prevent the undefined behavior - left shift of a negative value - stb#1500: stb_vorbis: Fix signed integer overflow Includes additional small fixes that I felt didn't warrant a separate PR.
