Log:
[SHELL32]
- Remove IExtractIconA_Constructor and rename IExtractIconW_Constructor to
GenericExtractIcon_CreateInstance which will handle both A and W.
- Make GenericExtractIcon_CreateInstance accept a pointer to a IShellFolder and a simple
pidl.
- Avoid using SHGetPathFromIDListW. Use ILGetDisplayNameExW instead. May make loading
icons for folders and exe files slightly faster as it does fewer I/O and less
allocations.
