SpectraLayers Performance on Mac: Transparency and Long-Term Direction

@nabw Here are the most relevant comments from @Robin_Lobel

As I understand it, it essentially boils down to the fact that you would need a separate version of SpectraLayers tailored exclusively to macOS. And this is likely not feasible, as it would double the development effort. And they don’t want to use Python, because it’s not part of SpectraLayers but runs as a separate application.
