mmm I understand the outline will be visible. I am more trying to reproduce the soft shadow effect I see on the dagger example on the page of this plugging, but for me it is looking different. It is like the gradiant is only being applied to the outside border of the outline, instead of the entire width of the outline. Lets say the width of the outline is 20px, the gradiant seems to only apply to the last 5pixels of the outline.
As for applying the transform on a proxy, let me try that and see if it changes the behavior of the outline. Thanks!
