Remarks

A context object that is meant to hold the scene information for the hovered viewport on a game thread, to be used by a gizmo later for hit testing. The organization mirrors FSceneView so that functions could be written in a templated way to use either FSceneView or UGizmoViewContext, though UGizmoViewContext only keeps the needed data.

Variables

FVector	GetViewUp()
bool	IsPerspectiveProjection()	As a function just for similarity with FSceneView.
void	ResetFromSceneView ( const FSceneView& SceneView )	Use this to reinitialize the object each frame for the hovered viewport.
