2.0: GTK3 and Compositing
The main changes
- Swap libraries and some code logic so simdock can work with wxWidgets-GTK3
- Enable composited transparent background. This seems to work only with a sufficient new wxWidgets version, like the current wxWidgets-3.2.4.
- The app should select bigger app icons by default now, if available
- Small bug fixes
Please note that the AppImage is likely to not work on composited systems yet, see #16
