Wow. Great fix! 💃

For future reference, the following gist contains a script that docker pull, run and produce a EMF figure using the Docker image built from commit cb9c1e4:

git clone https://gist.github.com/272c1cbf8db24e4c2aceffc91d137bf7.git
cd 272c1cbf8db24e4c2aceffc91d137bf7
./render.sh

Then inspect the resulting fig.emf or fig.emf.png. We see that the colorbar renders properly:

The above test should be automated and part of our test suite whenever we add image tests to Orca 🎉
