Dark mode for CFGs #64
Description
It would be nice to have a dark mode for the CFGs. Ideally, the extension would entirely conform to the selected theme in VSCode.
What we have tried so far:
- As Graphviz puts white background as default, this could be changed to transparent, but then all the elements' colours (edges, text etc.) should be overwritten one by one.
- Inverting the colours of the SVG with CSS but this would also invert when using light mode. It would be possible to have a separate option for GobPie if it should be using light or dark mode, but that would be just tedious duplication of settings.
- Using VSCode CSS colour variables. (This could maybe work using Graphviz stylesheets).
