Subject: [PATCH] Correctly scale the example dimension line in the widget

Draw the example dimension line into the correct position into its
widget. Before, moving the canvas, probably changing the zoom, then
entering line drawing mode and clicking on the dimension line widget in
the indicator panel would not render the example line correctly.
