feature request: horizontal/vertical lines

[Casper Hillerup Lyhne <hummesse gmail com>]

Hi.

I have been using Dia quite a bit to draw UML diagrams and such. There 
is a problem though. When i am done connecting all the objects with 
lines i always find myself zooming to ridiculous levels to align the 
objects so that the lines between them is either horizontal or vertical. 
This can't be solved through snap to grid since many objects has odd 
sizes that don't line up.

Because of this my feature request is this:
Please make a line that can only be vertical og horizontal.

That way i can snap the objects on to the (now perfectly vertical og 
horizontal) lines, and then i don't have to go through the aligning 
nightmare which is never perfect anyway.

regards
