Compute the interpolation factors <code>(t0, t1, t2)</code> in order to interpolate an arbitrary value over a given
triangle at the given point <code>(x, y)</code>.
<p>
This method takes in the 2D vertex positions of the three vertices of a triangle and stores in <code>dest</code> the
factors <code>(t0, t1, t2)</code> in the equation <code>v' = v0 * t0 + v1 * t1 + v2 * t2</code> where <code>(v0, v1, v2)</code> are
arbitrary (scalar or vector) values associated with the respective vertices of the triangle. The computed value <code>v'</code>
is the interpolated value at the given position <code>(x, y)</code>.
@param v0X
the x coordinate of the first triangle vertex
@param v0Y
the y coordinate of the first triangle vertex
@param v1X
the x coordinate of the second triangle vertex
@param v1Y
the y coordinate of the second triangle vertex
@param v2X
the x coordinate of the third triangle vertex
@param v2Y
the y coordinate of the third triangle vertex
@param x
the x coordinate of the point to interpolate at
@param y
the y coordinate of the point to interpolate at
@param dest
will hold the interpolation factors <code>(t0, t1, t2)</code>
@return dest
