1// nx_gx1b_page3d_gate.nx -- Gx-1b: the LIVE Nishi-Browser renders a FETCHED HTML page whose <img> element is 2// filled by the sovereign SW-GPU 3D rasterizer. This is the honest completion of nishi-browser-3d-surface: 3// our OWN browser engine (br_layout: HTML -> CSS cascade + box/flow layout; br_shot_png/br_draw_fb: paint -> 4// RGBA framebuffer -> PNG) lays out a REAL page (heading + paragraphs + image element) and the 3D scene is 5// painted into the element's box via the browser's OWN image path (page.bimg) -- driven by the page's live 6// layout, not a standalone gate.
