Path and geometry handling

[ff6347]

Some useful features for handling paths could be (suggested by @mariuswatz ):

• getting all vertices (and LR direction handlers)
• calculate centroid
• is point inside

What happens with compound paths?

An idea could be to use the same pattern as with words, lines etc.

pathpoints(obj, function(point){
  println(point);
})

It is a pity that we can't use normal ES5 js libs like turf.js for things like inside and centroid :(

Plz no support for super special stuff like compound paths ... very few people will use it, but lots of effort for implementing it.
