For random points, it won't be very useful for random lines unless the 
shape is guaranteed to be convex. For example, if you have a torus, it 
is very easy to have a line with the end points inside but which goes 
outside the shape. You need to check the end points and a lot of points 
along the line using the inside() function, or (faster and more 
accurate) use the trace() function to trace a ray along the line from 
one end point and check for an intersection closer than the other end 
point.
