make Handle in graphics script easier to click

[Craige_Hales]

Larger marker for Handle - the handle function makes a tiny square marker which is hard to hit with the mouse. Make it easier to drag a handle without hitting the exact center of the marker.

New Window( "Example",
    exx = 20,
    exy = 50;
    Graph Box(
        Frame Size( 200, 200 ),
        Handle(
            exx,
            exy,
            exx = x;
            exy = y;
        );
        Circle( {0, 0}, Sqrt( exx * exx + exy * exy ) );
    );
);

the bottom edge of the square marker seems out-of-bounds.

Same for Drag Markers!
One can increase th maker size - but one still needs to drag the Drag Marker at the center.
