FantaStick openGL line width

MIB's icon

Maybe I am doing something wrong, or am misunderstanding, but it seems that the max line width in openGL mode is 20. Is this intentional or a bug? In one of the helppatches for FantaStick the line width is set to 80, which leaves me to believe that it is a bug...

Thanks
