"Erode" effect to replace "Simple Choker"
It would be very nice to re-write the "Simple Choker" effect to perform more closely to the Nuke "Erode" node. Specifically the precision is much higher and the results more reliable. When using "Simple Choker" any feathering is lost and the matte becomes hard, it seems to exponentially get less effective the wider you go, and it does not keep the original shape of your mask very well (there seems to be a blurring effect which rounds out edges). On the other hand the Nuke "Erode" node works in pixels and no precision is lost in terms of your mask shape, so it is reliable and predictable. It is behaves much like "Mask Expansion" does for a mask (no precision is lost, it is measured in pixels, etc).
