SpotMapStageForm
How the audience surrounds the stage. This is what stops the renderer — and the "row F, centre, 12 rows back" descriptions — from assuming the stage is at the top of the map.
Values
endAudience on one side only: a proscenium house or a cinema.
thrustAudience on three sides.
inTheRoundAudience all the way around.
traverseAudience on two opposite sides.
