Determining Whether Two Areas Touch
The functions described in this section determine if two areas touch.
The GXTouchesRectanglePoint function determines whether the area covered by a rectangle touches a point.
The GXTouchesBoundsShape function determines whether the area covered by a rectangle touches a shape.
The GXTouchesShape function determines whether the area covered by one shape touches the area covered by another.
The GXIntersectShape function, which is described on page 4-107 in the section "Performing Geometric Arithmetic With Shapes," determines not only if two shapes intersect but also what their intersection is.
