When I run the main method for CurveManipulationRendererJ3D,
starting with the mouse in the plotting area, nothing happens when I
press and drag the right mouse button. If I move the mouse over the button
first, (no buttons pressed, just moving the mouse around) it activates
the CurveManipulationRenderer and I can draw.
Is there a command I can put in the code to automatically activate the
CurveManipulationRenderer even when the mouse starts in the plotting region?
