 
constructs the bisector of $$p and $$q.
The bisector is oriented in such a way that p lies on its
positive side. Precondition: p and q are not equal.  

 
constructs the bisector of the two lines $$l1 and $$l2. In the general case, the bisector has the direction of the vector which is the sum of the normalized directions of the two lines, and which passes through the intersection of l1 and l2. If l1 and l2 are parallel, then the bisector is defined as the line which has the same direction as l1, and which is at the same distance from l1 and l2. This function requires that Kernel::RT supports the sqrt() operation.
