Let the point be C (Cx,Cy) and the line be AB (Ax,Ay) to (Bx,By).
Let P be the point of perpendicular projection of C on AB. The parameter
r, which indicates P's position along AB, is computed by the dot product
r, which indicates P's position along AB, is computed by the dot product
of AC and AB divided by the square of the length of AB:
(1) AC dot AB
r = ---------
r = ---------
||AB||^2
r has the following meaning:
r=0 P = A
r=1 P = B
r<0 P is on the backward extension of AB
r>1 P is on the forward extension of AB
0<r<1 P is interior to AB
The length of a line segment in d dimensions, AB is computed by:
L = sqrt( (Bx-Ax)^2 + (By-Ay)^2 + ... + (Bd-Ad)^2)

so in 2D:
L = sqrt( (Bx-Ax)^2 + (By-Ay)^2 )
and the dot product of two vectors in d dimensions, U dot V is computed:
D = (Ux * Vx) + (Uy * Vy) + ... + (Ud * Vd)
so in 2D:
D = (Ux * Vx) + (Uy * Vy)
