glgui label wrapped

(glgui-label-wrapped g x y w h label fnt color . bgcolor)

glgui-label-wrapped creates a wrapping Label widget from a string. It behaves just like glgui-label and takes the same parameters. The only difference is that this function wraps the text. It starts the text in the upper left corner and continues in rows if the string is longer, until the box is full. Other attributes of the widget that can be set after this procedure are listed below the example.
