Subject: [PATCH] Sketcher: Preferences - add 3D view scaling factor

==================================================

In addition to the font size in pixels, which controls the 3D View font size (and indirectly the constraint icons),
it is now possible to configure a scaling factor controlling the width of geometry, axes, information layer, and
constraint lines.
