4645	Use blank pixels around lines to enhance readability	massimo ceraolo	Adeel Asghar	"In MA ticket 2162 there have been a discussion on the diode symbol. The IEC has the disadvantage that an erroneous connection between anode and cathode is hardly visible. Dropping that line solves this, but is against the effort of making Modelica symbols as IEC compliant as possible.
The decision was to keep the IEC symbol.

However it may occur to newbies that a line is inadvertently drawn between anode and cathode. This is crazy but happens. It produces an issue which is difficult to spot.

Dymola solves this using a graphical representation which does some difference between a correct diode and a short circuit diode (Dymola.png) 
OMEdit does not make any difference (OM.png).

I think that Dymla simply uses some blank pixels at the sides of connecting lines: in this way the lines are ""detached"" from any underlying other drawing element.

Is it possible to consider something also for OMEdit?
Not only would this enhance readability of diodes and GTOs, but, more in general, readability of all diagrams in which connecting lines are drawn over other elements. 
Important is the case of connecting lines intersections: compare the way intersections are viewed in Dynmola and OM for the file ""crossingLines.mo""
