interpolateTriangle

Bilinearly interpolate the two-dimensional vector <i>f</i> over the given triangle and store the result in <code>dest</code>. <p> Reference: <a href="https://en.wikipedia.org/wiki/Barycentric_coordinate_system">https://en.wikipedia.org/</a>

@param v0X the x coordinate of the first triangle vertex @param v0Y the y coordinate of the first triangle vertex @param f0X the x component of the value of <i>f</i> at the first vertex @param f0Y the y component of the value of <i>f</i> at the first vertex @param v1X the x coordinate of the second triangle vertex @param v1Y the y coordinate of the second triangle vertex @param f1X the x component of the value of <i>f</i> at the second vertex @param f1Y the y component of the value of <i>f</i> at the second vertex @param v2X the x coordinate of the third triangle vertex @param v2Y the y coordinate of the third triangle vertex @param f2X the x component of the value of <i>f</i> at the third vertex @param f2Y the y component of the value of <i>f</i> at the third vertex @param x the x coordinate of the point to interpolate <i>f</i> at @param y the y coordinate of the point to interpolate <i>f</i> at @param dest will hold the interpolation result @return dest
