Description
Calculates the 2d bisect vector of an angle defined by three 2d points
(pt1, center, pt2).
center is the apex of the angle formed by the 2d vectors (center, pt1) and
(center, pt2).
Plugin Prototype

Parameters
pt1 [Input]
2d point 1
center [Input]
apex of the angle
pt2 [Input]
2d point 2

Returns
Error codes
FZ_MATH_ERR_ZERO_LEN_VEC - lines from pt1 to center or center to pt2 are zero length
FZ_MATH_ERR_VEC_PARALLEL - pt1, center, pt2 are colinear
