Is it possible to draw a parabola respecting the border shape of the node?
In a simple line or arc this is possible by using nodes with `inner sep` as endpoints, but the parabola doesn't care about this separation option.

Here is an example, which shows the difference. I would like to have the parabola like the arc.

```
\documentclass{standalone}
\usepackage{tikz}
\begin{document}
\begin{tikzpicture}
  \node[circle,fill=white,draw=black,inner sep=2mm] at (0.0,0.0) (p1) {};
  \node[draw=none] at (1.0,1.0) (p2) {};
  \node[circle,fill=white,draw=black,inner sep=2mm] at (3.0,0.0) (p3) {};
  \draw[->] (p1) parabola bend (p2) (p3);
  \draw[->] (p1) -- (p3);
\end{tikzpicture}
\end{document}

```
