Small Change of the Trackball apply interface. It does no more require a bool to specify if the trackball icon has to be drawn because it is always wrong to draw the trackball at the apply time (two reasons, antialiasing and transparency and zbuffer preservation) So now the standard call is just Apply() without the useless bool parameters.

Updated also all the vcg samples using the trackball
