-- Convert zone threshold fields (MinAlarmPixels, etc.) from pixel counts
-- to percentages of zone area, matching the coordinate percentage migration
-- done in zm_update-1.39.2.sql.
--
-- The Zones.Area column is often 0 (never populated, or not used by the C++
-- daemon which calculates polygon area at runtime from coordinates).  So we
-- compute the polygon area directly from the percentage coordinates using the
-- shoelace formula, then derive the pixel area to convert thresholds.
--
-- new_percent = old_pixel_count * 100 / zone_pixel_area
-- zone_pixel_area = pct_poly_area * monitor_width * monitor_height / 10000
--
-- Only converts zones with percentage coordinates (contain '.') that still
-- have pixel-scale threshold values (any value > 100 can't be a percentage).
