            alpha 67   win xp pro   -----------------------------------   void setup() {   size(600, 600);   noStroke();   }      void loop() {   fill(color(255,0,0),0);   rect(mouseX,mouseY,100,100);   }   -----------------------------------      as you can see the alpha for fill is set to "0".   moving around the mouse still creates rects in light grey.   why?   please help.      frank

            the "why" is rounding error in the graphics engine.       other folks have run into this, i'll see what i can do about cleaning it up.
