Better dark theme support #58
Description
Currently, the graph views keep a light background for the default Eclipse Dark theme. Also, the perspective icon is not easy to recognize.
It would be nice if the graphs would integrate better into the overall dark appearance. I'm unsure what the background, node and edge colors should be in order to be equivalent to the current appearance. Suggestions are welcome!
The platform here is Windows 10, perhaps this is part of the issue.
