This behavior removes the 1 pixel black border from projectors.

-- This behaviour does the following:
-- If it finds the stage to be smaller or equal than the current screenresolution
-- it resizes the stage to that resolution, but sets the drawrect to the source.
-- It thereby removes the dreaded 1 pixel black border. If the screenresolution is
-- smaller than the stage, this behaviour only rescales the stage to fit the displayresolution.

-- This behaviour is set to only work in projector mode and is not intended to work
-- as a shockwave movie.

-- Events
on prepareFrame(me)
  if me.isProjector() then
    me.redrawStage()
  end if
end

-- Private
on isBiggerThanScreen(me, aRect)
  -- Check if the stage is bigger than the screen resolution
  return (aRect.width > (the desktopRectList)[1].width)
end

on isProjector(me)
  -- check if running in projector mode
  return not (the runMode contains "author")
end

on redrawStage(me)
  lRect = (the desktopRectList)[1]
  if me.isBiggerThanScreen((the stage).sourceRect) then
    -- set the new drawrect to the size of the screen resolution
    lNewDrawRect = lRect
  else
    -- set the new drawRect to the sourcerect of the stage
    lNewDrawRect = (the stage).sourceRect
  end if
  -- First resize the stage
  (the stage).rect = lRect
  -- Then resize the drawrect
  (the stage).drawRect = lNewDrawRect
