Feature Request: Guides (lines coming out of rulers, like gimp and inkscape)

a simple feature suggestion for dia. I think I first saw this in Visio,
but it's been many many years since using Windows so I might be mistaken.
Anyway, in Visio there are two moveable lines - one vertical and one
horizontal. They don't do anything, you just move them around. But
they're really useful for two things: (1) Lining things up so they
line up vertically or horizontally, and (2) Marking out the "edge"
of the paper, so you can mentally say to yourself "don't draw anything
beyond this edge".

So in effect, this would be just like a line object, except that its draw routine would somehow detect that the canvas it's been drawing on is an interactive canvas (in which case it draws) or it's not (in which case it does nothing).
Hmmm. Sounds interesting (this dynamic_cast
sound difficult now we've got GObject renderers, thanks to Hans). Besides,
this doesn't even need to have all the formatting properties of lines, just
something to make obvious that it's a formatting aid, not something printed
(maybe even a static label property to remind this to the user).

That's an interesting idea. Maybe tear-off the diagram-side rulers. Not high on my list, though. If you want to do this, go ahead.
