  # How much should the text be offset?

  #
  #-----------------------------------------------------------------------------
  # What color should the text be? [R, G, B] -OR- windowskin color index
  # ex: TEXTCOLOR = 0   on a fresh project would make the text white, and
  #     TEXTCOLOR = 1   would make it blue.
  # also:
  #     TEXTCOLOR = [255, 255, 255]   makes text white
  #     TEXTCOLOR = [0, 0, 0]         makes text black (will look bad unless
  #                                   HIDE_TEXT_SHADOW = true)

  # There's this really annoying blurry outline that shows up around stuff...
