<summary>
Obtains the total size of a file.
</summary>
<param name="fileSize">Receives the total size of the file.</param>
<returns>
Standard HRESULT error code.
</returns>
<remarks>
Implementing GetFileSize() for asynchronously loaded font files may require
downloading the complete file contents, therefore this method should only be used for operations that
either require complete font file to be loaded (e.g., copying a font file) or need to make
decisions based on the value of the file size (e.g., validation against a persisted file size).
