this makes the kscreensaver template quite useless. it generates a 
blank() method with the comment "put code to render your screensaver 
here".
so i made my own member function, called it once from within blank(), 
then connected my function with a timer. on the console i see that my 
method is called at the appropriate intervals, but the window itself 
stays black.


so, how am i supposed to do it?
