    rounded ends are the only kind that compose nicely when drawn that way


Oooh, that's interesting. After sending the first email I'd actually
gone ahead and hacked make-pen% to always use the square cap -- which
looked "matplotlib good" for my plots -- and was planning to expose that
parameter in a pull request. But I won't anymore.

For the record, my actual problem was with 2 specific points:

    1. Plot lines extended slightly past the x/y axes

Is this actually a clipping issue?

    2. Dashed horizontal rules looked better as square lines

True. So do extra axes, plot boundaries and tick lines.

I'd be perfectly happy if all the decorations, and renderers that produce decoration-looking things like axis lines and rules, always used square caps. Maybe even 2D rectangles and other stuff that always draw just horizontal and vertical lines. I wouldn't even want a parameter for changing them back, pursuant to Plot's "looks great without users having to think about making it look great" design goal.
