- 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.
