code to load and set the HICON into the window. Currently, an .ico file with the same name as the image specified in NSIcon or CFBundleIconName needs to be provided in the resources. NOTE: An enhancement to generate this from the app icon will follow shortly. git-svn-id: svn+ssh://svn.gna.org/svn/gnustep/libs/back/trunk@29396 72102866-910b-0410-8b05-ffd578937521
