I've looked only at 09_user_ani_cursor.diff.txt:

1. CURSORICON_LoadFromFile returns 0 on failure, so load_ani should return 0
on failure as well not INVALID_HANDLE_VALUE (which usually is returned only
for kernel objects).

2. the loop in riff_find_chunk uses memcmp to compare DWORDs, comparing
DWORD values directly is more efficient, and alignment is not a problem
since all the fields and chunks are DWORD aligned. Making ptr of a type
DWORD should help with that, although that makes pointer arithmetic
slightly more tricky, that's still will look more readable IMO.
