- Make the module global and allow usage from anywhere.
- Remove the matrix API for thread safety reason
- Add lifetime management
- Make display linked to the overlays for easy toggling
## Notes
- Lifetime is in redraw. If there is 4 viewport redrawing, the lifetime decrement by 4 for each window redraw. This allows one viewport to be producer and another one being the consumer.
- Display happens at the start of overlays. Any added visuals inside of the overlays drawing functions will be displayed the next redraw.
- Redraw is not given to happen. It is only given if there is some scene / render update which tags the viewport to redraw.
- Persistent lines are not reset on file load.
