-- This file returns an ActorFrame that holds a few objects.

-- Since I like to collapse similar code, here is a simple example:
local lineWidth = SCREEN_WIDTH*0.9;
-- previously, I had this set to SCREEN_WIDTH*0.8 in each of the
-- Def.Quad blocks below. Now I just use lineWidth and I get two advantages:
-- 1) I can change it and it takes effect in multiple places.
-- 2) I get a human readable name out of it.
-- It makes your code easier to read and work with.

local lineTime = 0.625;
-- same with this code.
