It would be good to have terracer functionality like JOSM's, even if we just restrict it to simple rectangles for now.

First of all we need to implement a "slice" action for areas: given nodes A1 and B1, slice the polygon into two along a new line A1-B1.

Then we can implement a terracer like this:

find the longest edge (A)
find the opposite edge (B)
interpolate nodes A1, A2, A3... and B1, B2, B3...
slice polygon A1-B1
slice remainder A2-B2
slice remainder A3-B3
etc.
