paint tools should support "smudging" as they paint.
Submitted by Adrian Likins
The idea for this RFE is to allow paint tools to "smudge" there brush strokes to allow a more realistic result.
Ideally, this would allow the stroke to both paint normally, and "smudge" at the same time.
I have a rough patch that allows paintbrush to paint on the first _motion() and then smudge on the rest. The result is a somewhat more interesting and realistic stroke than simply using a brush with a very low spacing.
