I would like to use a `path picture` for all paths in a `tikzpicture`. If I manually add the `path picture` to all `\path`s, things work as expected.

Now I'm wondering if this can be automated. Naively, I tried to add the path picture via `every path/.style={...}`, but this tries to insert the image a lot more often than the three `\path`s in the `tikzpicture` and ultimately results in:

```
! TeX capacity exceeded, sorry [grouping levels=255].
<to be read again> 
                   {
l.32   \path (0,0) rectangle ++(1,1);
```

So I guess it goes into a loop when it tried to use paths to draw the path picture?

Is there any other way to apply a `path picture` to every `\path` (there are no `\node`s or other elements in this `tikzpicture`)?

### Test document:

```
\documentclass{standalone}
\usepackage{tikz}

\begin{document}

% working
\begin{tikzpicture}[
  quack/.style={
    path picture={%
      \node[anchor=south west,inner sep=0pt] at (0,0) {\includegraphics[width=3cm,height=3cm]{example-grid-100x100bp}};
    }
  }
]
  \path[quack] (0,0) rectangle ++(1,1);
  \path[quack] (1,1) rectangle ++(1,1);
  \path[quack] (2,2) rectangle ++(1,1);
\end{tikzpicture}

% working
\begin{tikzpicture}[every path/.style={draw=red}]
  \path (0,0) rectangle ++(1,1);
  \path (1,1) rectangle ++(1,1);
  \path (2,2) rectangle ++(1,1);
\end{tikzpicture}

% problem
\begin{tikzpicture}[every path/.style={
    path picture={%
      \node[anchor=south west,inner sep=0pt] at (0,0) {\includegraphics[width=3cm,height=3cm]{example-grid-100x100bp}};
    }
}]
  \path (0,0) rectangle ++(1,1);
  \path (1,1) rectangle ++(1,1);
  \path (2,2) rectangle ++(1,1);
\end{tikzpicture}

\end{document}
```
