Issue 156 solved. Added width, height and points as parameter to svg and pdf output mode. Width and height have an effact on the width and height of the export, points is a boolean property which enables/disables the drawing of data points. gnv-artifacts/trunk@616 c6561f87-3c4e-4783-a992-168aeb5c3f6f
