Is there a video generator for lines?

Question

I'm still drawing circles, squares, and lines to overlay on my videos. Some time ago when I needed to make circles and squares, but didn't know how, someone here (Piero I think) told me about a great plug-in generator called Frames for just that purpose, which I installed in FCE and now use a lot (I forget the author of that wonderful program, but it appears under Video Generators > pf > Frames).
Well, now I'd like an easier way to draw lines on my videos than creating mattes and cropping them down to a sliver, or creating them in Photoshop on transparent backgrounds and then importing them into FCE as .psd files. Those methods are slow and tedious.
What I'd really like is a line generator on the order of that great pf plug-in for creating frames, only this one would be for lines. And ideally it would be able to create control points on a generated line so that you could curve and bend the line into various shapes, for example to match the twists and turns of a road on a map, or to make arcs and S-shapes. And it should have arrowheads available to put on the ends for pointing at things: arrows.
Does anyone know of any such line generator available anywhere for Final Cut Express?

Answer 1

That arrow generator is really nice, Ian, thanks much. That solves one of my problems; I was making arrows in Photoshop and importing them, which was tedious. But now with this generator I can quickly make any size or length arrow easily, right inside FCE. I notice that the size of the arrow after rendering is slightly smaller and thinner than it appears pre-rendered, but once you get used to that, and compensate for it a little in your design, you can make arrows of just the right size needed. Very nice!
Now if there were only a generator for curved, bent, or squiggly lines, able to be shaped as desired, for example to create a line to match the shape of a road as seen on a map, or an aerial photograph, I'd be all fixed. I don't suppose any such generator exists yet, though, so I'm still stuck with Photoshop for that, for now.
