/**
 * A "Save As" dialog for saving files in a variety of formats.
 * This dialog is designed to work in both signed and unsigned web start
 * applications, as well as standalone applications. WebStart puts some limits
 * on the possible functionality, for example we can get the full file name,
 * and it has limited support for setting file filters, so the dialog has
 * to work around these limitations.
