possibly check for drawPath before creating the dash object?

I'll just do them at the same time, there's no reason not to. Done.

+            if dash then
+                if t.verb == "drawPath" then
+                    dashes = dashes + 1
+                    pathPieces[dashes] = 0
+
+                    local path = t.path
+                    local fillpath = paint:getFillPath(path)
+                    local verbs = fillpath:getVerbs()
+                    for _, verb in ipairs(verbs) do
+                        if verb == "move" or verb == "close" then

[reed1, 2016/08/01 19:36:29]

why do you look for close?

[Harry Stern, 2016/08/01 20:58:23]

(Mike and I discussed this and he told me that we aren't necessarily doing a
close for each segment of the dash)

I will just fix the count at the end. Done.

+                           pathPieces[dashes] = pathPieces[dashes] + 1
