.res, consists of raw resource data chunks, each preceeded by resource header. Resource has three main properties encoded as unsigned 16bit integer number: type, name and language.
.ResType is 0xFFFF, ResTypeLength is 2 and the second word
specifies resource type identifier (standard or custom numeric id). Otherwise it is a zero-terminated Unichar string.
.ResName is 0xFFFF, ResNameLength is 2 and the second word
specifies resource name identifier (numeric id). Otherwise it is a zero-terminated Unichar string.
.ResName member is not DWORD aligned, one padding zero-word must be added.
