Put the editor viewport into a top-down orthographic plan view

Browse Source 
Opening the Plan tool now switches the whole colour pass to an orthographic
projection and pins the camera looking straight down, so the plan is drawn
against the loaded scenery rather than in a window of its own. Closing the
tool hands the camera's orientation back; leaving the editor clears the view
outright. The wheel changes how much ground fits on screen instead of moving
the camera, which with no perspective would change nothing but the clipping.

Both configured backends follow: the experimental renderer swaps the pass
projection (and fits its shadow cascades to it), the modern GL renderer uses
its existing ortho helpers. Everything reading the pass projection - the
mouse ray, the frustum test - picks the change up on its own.

The experimental renderer also publishes its colour pass camera now, which
it previously left at the interface defaults, so overlays can place world
points on screen.
