-- Probe: the reported grass along the TOP of the frame in GO-style
-- battles on ROUTE 6.
--
-- The capture seat is a different camera from the battle's own: the "tele"
-- rig stands 145 world px back at a height of 37.9 (well over two cells,
-- clear of anything that grows on the ground), while the head-on capture
-- seat stands 46 back at a height of 13 -- BELOW the top of a 16px grass
-- tuft or hedge. On a route lined with the stuff, the eye is inside it.
--
-- So: stage a capture at several spots along Route 6 and record where the
-- eye actually is relative to the ground, with a shot of each.
