How to wrap text around part of a figure

Question

I am looking for wrapping some text around part of a figure in the following way:

Lorem ipsum dolor sit amet, consectetur adipiscing elit.
Aenean quis mi ut elit interdum imperdiet quis non ante.
+---------------------------+ +-------------------------+
|                           | |                         |
|                           | |                         |
|                           | |                         |
+---------------------------+ +-------------------------|
      (a) subfigure a              (b) subfigure b
                              +------------------------+
Sed imperdiet, sapien quis    |                        |
viverra rhoncus, tellus dui   |                        |
dictum nisl, at porta purus   |                        |
ipsum ac turpis. Fusce auctor |         FIGURE         |
ullamcorper adipiscing. Nunc  |          HERE          |
non quam ac orci egestas con- |                        |
sequat ut eget quam. Cras     +------------------------+
blandit condimentum ornare.         (c) subfigure c
Curabitur aliquam, nulla sit 
amet iaculis tristique, mi        Figure 1: demo
nulla auctor magna, sit amet imperdiet ante arcu a libero.

The example here How to wrap text around a subfigure? has it only for equal-sized subfigures (which, I usually do simply by putting subfloat in my wrapfigure). Is there any way to do what I am suggesting. I am on Fedora 29 which has the texlive distribution. Thanks in advance for any suggestions or pointers.

The suggestion given works, but not for the subfig package (which uses subfloat that I thought was recommended over subfigure.)

Here is the example text:

\documentclass{article}
\usepackage{graphicx}
\usepackage{caption}
\usepackage{lipsum}
\usepackage{wrapfig}
\usepackage{verbatim,subfig}
\begin{document}
\lipsum[1]
\begin{figure}[h]\centering\ContinuedFloat*
\mbox{  \subfloat[]{\label{a}\includegraphics[draft,width=0.5\textwidth]{foo.png}}
  \subfloat[]{\label{b}\includegraphics[draft,width=0.5\textwidth]{foo.png}}}
\end{figure}
\begin{wrapfigure}{r}{0.5\textwidth}\centering\ContinuedFloat
  \subfloat[]{\label{c}\includegraphics[draft,width=0.5\textwidth]{foo.png}}
  \caption{Demo}
  \label{fig}
\end{wrapfigure}
\lipsum[2]
\end{document}

The counter deprecates every time ContinuedFloats in used.

I could perhaps add to the figure counter everytime continuedFloats is used but that does not seem kosher to me. I like clean solutions if available.

Have you considered making use of \ContinuedFloat from the caption package (without defining a different label format for continued floats)?

Code

\documentclass{article}
\usepackage{geometry}
\usepackage{graphicx}
\usepackage{caption}
\usepackage{subcaption}
\usepackage{lipsum}
\usepackage{wrapfig}


\begin{document}
    \lipsum[1]
\begin{figure}[h]\centering\ContinuedFloat*
  \begin{subfigure}[b]{0.5\textwidth}\centering
  \includegraphics[draft]{foo.png}
    \caption{}
    \label{a}
  \end{subfigure}%
  \begin{subfigure}[b]{0.5\textwidth}\centering
  \includegraphics[draft]{foo.png}
    \caption{}
    \label{b}
  \end{subfigure}
\end{figure}
\begin{wrapfigure}{r}{0.5\textwidth}\centering\ContinuedFloat
    \begin{subfigure}{0.5\textwidth}\centering
      \includegraphics[draft]{foo.png}
      \caption{}
      \label{c}
    \end{subfigure}
    \caption{Demo}
    \label{fig}
\end{wrapfigure}
    \lipsum[2]
\end{document}

Output:

More info on \ContinuedFloat in the LaTeX Wikibook: 8 Figures in multiple parts.

Edit: User wants a working example using the subfig package.

The problem with your current example is that the first figure environment has no caption. The \phantomcaption command may be used to create a hidden caption which should clear up your issue:

\documentclass{article}
\usepackage{geometry}
\usepackage{graphicx}
\usepackage{caption}
\usepackage{lipsum}
\usepackage{wrapfig}
\usepackage{subfig}


\begin{document}
    \lipsum[1]
\begin{figure}[h]\centering
  % \ContinuedFloat* % Remove this.
  \subfloat[][]{\includegraphics[draft]{foo.png}}
  \qquad
  \subfloat[][]{\includegraphics[draft]{foo.png}}
  \phantomcaption
\end{figure}
\begin{wrapfigure}{r}{0.5\textwidth}\ContinuedFloat\centering
  \subfloat[][]{\includegraphics[draft]{foo.png}}
    \caption{Demo}
    \label{fig}
\end{wrapfigure}
    \lipsum[2]
\end{document}

(also, remove the \ContinuedFloat* in the figure environment - it appears subfig does not use this - see section 2.2.3 of the subfig documentation).
