clipping of the orientation grid can be clearly seen as a line when zooming out of the scene

[rob-bateman]

Steps to reproduce

• open a new document
• zoom out

you can see the farfield clipping line as a horizontal boundary across the grid where presumably the scene grid is clipped and the other grid is overlaid

would it not be better to just have one grid that was renderered outside the clipped view? that way the orientation grid would never be clipped in this way
