line style suggestion: double straight lines

[Neil Zanella <nzanella cs mun ca>]

Hello,

It would be nice if users could click on the Create Line button, add a 
line by clicking on the diagram, and then double click on the line and
select an option called "double" from the Line Style drop down menu.
This would enable users to create straight double lines in diagrams
such as ER diagrams where either double lines or thickened lines are
often user to enforce total participation. The double lines provided
in the ER-diagram specific tools button box are different in that
they bend which is probably not what most users would like to use
in their ER-diagrams. Allowing ordinary lines to be displayed as
double lines would be great though.

Thanks for dia!

Neil
