generalized drawing back-end for array objects, i.e. _zLineArray, _zCirclePencil ,etc.
Methods defined in zdrawArray
iterate through the objects of the array and call the objects _redraw routine to redraw
at its current position
the objects of the array get initialized on creation by the array's init() method - this is only
to mark the array itself as initialized
export the objects of the scene's arrays to PovRay SDL
for more information.
