GraphStyle
The colors and strokes GraphCanvas draws its own overlays with.
In the namespace widgets::graph. Declared in src/libs/libwidgets/graph/IGraphHost.hpp.
Detailed description
The canvas draws exactly three things of its own — the background, the in-progress connection line, and the lasso rectangle. Everything else is the host's, through IGraphHost::draw(). The host supplies these so a theme lives in one place per application and not in this widget.
