about
nx_geo_raster_gate.nx -- GATE for GEO-020 raster render (integer scanline fill) on an 8x8 grid:
rectangle [rows 1..4) x [cols 1..5) -> filled count == 3*4 == 12; (2,2) filled, (0,0) & (5,5) empty
right triangle (0,0),(0,4),(4,0) -> filled count == 4+3+2+1 == 10 (triangular number);
(0,0) & (0,3) filled, (3,3) empty
Exact integer pixel counts -> deterministic coverage, no float seam/overlap.
Evidence -> knowledge/status/geo_raster.log (GEORASTERGATE authored=organ ... verdict=GREEN).
