Viewport Origin Axis

It would handy to have a way to show an axis handle at the origin of the 3D Viewport.

  • This should include any 3D Viewport, like the one in Blueprint.

  • Add controls to resize it.

  • Add controls to set it as an overlay.

  • Sometimes the infinite red and green lines is kinda hard to see.

  • Add a way to increase/decrease the visibility of this.

  • Option to show a blue infinite z-axis line.
