in reply to Tk::Text. How to find out if char is visible?

I can't really help in any event, but can you clarify - "visible" as in "a different colour than the background" or "visible" as in "on screen"?

map{$a=1-$_/10;map{$d=$a;$e=$b=$_/20-2;map{($d,$e)=(2*$d*$e+$a,$e**2 -$d**2+$b);$c=$d**2+$e**2>4?$d=8:_}1..50;print$c}0..59;print$/}0..20
