Following your trail example http://dl.dropbox.com/u/5426011/examples%208/canvasTrail.capx
I tried to replicate the trail effect http://www.eli0s.com/Tests/TowerLaser.capx
and I was wondering why there is a trace left visible behind? Shouldn't the destination out object add to its self to the point that the trail is completely transparent?
In an other case, I tried to fill the canvas with a color ("rbga(0,0,0,0.1)"), the canvas does get darker and darker but the same kind of trace is being left behind.
Any ideas? Does this happens to anybody else? Am I doing something wrong here, because even on R0J0hound example the same thing happens?
