//
// Resource directory consists of two counts, following by a variable length
// array of directory entries. The first count is the number of entries at
// beginning of the array that have actual names associated with each entry.
// The entries are in ascending order, case insensitive strings. The second
// count is the number of entries that immediately follow the named entries.
// This second count identifies the number of entries that have 16-bit integer
// Ids as their name. These entries are also sorted in ascending order.
//
// This structure allows fast lookup by either name or number, but for any
// given resource entry only one form of lookup is supported, not both.
// This is consistant with the syntax of the .RC file and the .RES file.
//
//
// Each directory contains the 32-bit Name of the entry and an offset,
// relative to the beginning of the resource directory of the data associated
// with this directory entry. If the name of the entry is an actual text
// string instead of an integer Id, then the high order bit of the name field
// 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
