-- Horizontal region encoder
--
-- This encoder can change the horizontal region value coming out of the horz
-- ROM before it is used to address the color ROM. The horizontal region is
-- modified under 3 conditions.
--
-- First, if the horizontal region is the first (leftmost) colorbar, then the
-- two user_opt inputs are applied to modify the horizontal region to affect
-- the color generated by the color ROM.
--
-- Second, if the region is the first sample of first line of the first field
-- of an even frame and the cable equalization pattern is being drawn, then
-- the sample must be drawn differently in order to provide both DC levels of
-- the cable equalization pattern. The horizontal ROM will indicate this
-- region by generating a region code of HRGN_CEQ_POL_0. The encoder will
-- normally change this to HRGN_CEQ_POL_0, unless this is the first active
-- line of the first field of an even frame, in which case it will output
-- HRGN_CEQ_POL_1 to the color ROM.
--
-- Third, the color ROM needs to know the sense of the field bit in order to
-- properly generate the XYZ word of EAVs and SAVs. The v_band does not carry
-- the field information into the color ROM, so the field bit from the vertical
-- ROM is used to modify the horizontal region during the second half of the
-- EAV and SAV regions to indicate the status of the field bit.
--
