    GML Fast point is inside polygon [QUESTION]

    Is there a fast way to detect if a point is inside a given polygon... a script like point_inside_polygon(x, y, [x1, y1, x2, y2, x3, y3, x4, y4, x5, y5]); returning a Boolean, I was looking through the manual... and I am admired it doesn't exist one.
