continuous edge with actionscript? - DrawingAPI

[Kirl]

How do I set the linestyle to draw with a continuous outline (contour/ wet edge in PS)? So when you paint over a previous stroke the border doesn't cross but it will put a single border around the contours of the whole shape. I can't find it in the docs because I don't know what it's called...

Anybody know what I'm referring to?

Let me try this again,

Say I wanted to draw a cartoony cloud with the drawing API by placing several big dots (actualy 1px long lines, with a thick linestyle) close together so they overlap some. I should have a simple cloud made of dots. I was hoping to make such a contour, by using the actionscript alternative for a thick white brush with a thin black outline and painting the dots to the same MC/shape.

Problem is, I don't know of any border/outline kind of property in linestyle?

I can select this in the editor (thick white brush + black outline), but is this possible with actionscript as well?
