-- ArcHUDRingTemplate_ Ring Template
----------------------------------------------------------------------
--
-- Template code for partial ring display
--
-- Divides the ring up into four quadrants:
--   Q1-TopRight Q2-BottomRight Q3-BottomLeft Q4-TopLeft
--
-- Other terminology:
--   self.radius - The outer radius of the ring (Also the texture width)
--   self.ringFactor - The ratio of inner radius/outer radius

---------------------------------------------------------------------------
-- QUADRANT MAPPING FUNCTIONS
--   The subsetting code is all written relative to the first quandrant, but
--   each quadrant has a pair of functions to manage mapping location and
--   texture operations from that 'normalized' coordinate system into the
--   appropriate one for the quadrant in question
--
-- SUBSET FUNCTION
--   self function displays a subset of a quadrant, using a subset of a
--   texture (The texture subsetting is optional, so the same function
--   can be used for slice stretching). Note self does not issue a
--   ClearAllPoints.
--
--   setSubsetFuncs[quadrant](tex, parname, radius, xlo, xhi, ylo, yhi, notex)
--
--   Parameters:
--     tex      - The texture object
--     parname  - The name of the texture's parent (for SetPoint use)
--     radius   - The outer radius of the ring (i.e. texture width & height)
--     xlo, xhi - X Coordinate bounds (from center of the ring)
--     ylo, yhi - Y Coordinate bounds (From center of the ring)
--     notex    - (OPTIONAL) If present and true, do not set texture coords.
--                just change points.
--
-- SLICE FUNCTION
--   self function sets the texture coordinates for a slice texture, so that
--   it's correctly oriented for the quadrant.
--
--   setSliceFuncs[quadrant](tex)
--
--   Parameters:
--     tex      - The slice texture object
