New issue 208: Point from X and Y needs vertical bar to help select point for X vertical value. https://bitbucket.org/valentinateam/valentina/issue/208/point-from-x-and-y-needs-vertical-bar-to

Susan Spencer:

When selected the Point from X and Y tool should show a vertical bar to guide the user in selecting the 1st point to derive the X vertical value.
Currently, as soon as the 1st point is selected, both the vertical bar and a horizontal bar are displayed. The vertical bar should be displayed prior to selecting the 1st point.
