7 * Changes the style of the current output stream. @val should be one of
8 * #style_Normal, #style_Emphasized, #style_Preformatted, #style_Header,
9 * #style_Subheader, #style_Alert, #style_Note, #style_BlockQuote, #style_Input,
10 * #style_User1, or #style_User2. However, any value is actually legal; if the
11 * library does not recognize the style value, it will treat it as
12 * #style_Normal. (This policy allows for the future definition of styles
13 * without breaking old Glk libraries.)
