Unless I'm incorrect on this, and I could very well be, I think that the wxDC API really just uses wxGraphicsContext under the hood in #wxWidgets on Linux w/ GTK 3 under Wayland. Not sure if it's the same for GTK under X11, but I know it's that way for macOS. This is for wxWidgets 3.2.10.
The only different where it'll actually matter likely is on #Windows I assume, where wxDC uses GDI and wxGraphicsContext can use either GDI+ (default) or Direct2D.
