-// is set to one and the low order 31-bits are an offset, relative to the
-// beginning of the resource directory of the string, which is of type
-// IMAGE_RESOURCE_DIRECTORY_STRING. Otherwise the high bit is clear and the
-// low-order 16-bits are the integer Id that identify this resource directory
-// entry. If the directory entry is yet another resource directory (i.e. a
-// subdirectory), then the high order bit of the offset field will be
-// set to indicate this. Otherwise the high bit is clear and the offset
