pipes go into filling all 3x3 and all is lost

 no, i do need direction.
 
 ok, let's go lunch maybe, and maybe it will be a place with a power outlet as well
+** all is bad.
+i guess my model is unfit.
+
+what if. i had only 'forward' movement,
+and then Next would sometimes return 'forward', and sometimes 'right', 'forward'
+
+then.
+i'll need to store current directoin,
+have function to rotate it.
+
+and do 'forward' on coords based on the current direction
+
+and that would be NextPathCell()
+
+but from same how would i distinguish between being on top or bottom for -J
+i'll need to remember whether outer is to the 'left' or 'right' of the path
+and then if path turns into outer - just turn, don't do 'forward'
+and if path torns out of outer - do "big turn"
+
+maybe there's an easy check here?
+if path
+** and one more idea.
+i could do without 'walking' the outer pointer.
+i could mark all outer around the path element.
+based on where the outer is located
+and there are two possibilities.
+i could even maybe mark them as 3x3
+
+i stay on the path element.
+i check what are the 'O' in it's 3x3
+and fill in other of same area as 'O' and move on to next
+
+yeah, i think i like that.
+
+i will have a function that takes the path element.
+select the template
+then go through 3x3 around the path element, if sees element with .isOuter == true saves the name of the area,
+then for each found out area mark them all as 'O'
