ViewportLayout

Remarks

A pane is a whole SceneViewport, not a camera. Doc 11 asks for "multiple simultaneous viewports with independent cameras and render modes", and the second half of that is what forces it: a render mode is stage state and a RenderStage belongs to the render system, so a pane that wanted its own mode needs its own stage as well as its own view. Sharing anything less than the whole pane makes the second pane silently change the first.

The quad layout's three orthographic panes are set up once, on creation. Top, front and side with an orthographic projection is what everybody means by a four-pane layout, and a layout that came up as four identical perspective views is one that every user then configures by hand.

⚠ Only the focused pane is driven by the keyboard. Two panes both taking WASD would fly both cameras, and a viewport is focusable precisely so that "which one" has an answer.
