Computes the intersection between a line and a rectangle.

The intersection will contain the parameters 't1' of the line in range [0,1].

Parameters:

a0 - point 0 of the line

a1 - point 1 of the line

r0 - corner point 0 of the rectangle

r1 - corner point 1 of the rectangle

Returns:

computed intersection
