## Draw 3D point on the current axis.
##
## drawPoint3d(X, Y, Z)
## will draw points defined by coordinates X and Y.
## X and Y are N*1 array, with N being number of points to be drawn.
##
## drawPoint3d(COORD)
## packs coordinates in a single [N*3] array.
##
## drawPoint3d(..., OPT)
## will draw each point with given option. OPT is a string compatible with
## 'plot' model.
##
## H = drawPoint3d(...)
## Also return a handle to each of the drawn points.
