render3d: the terrain's questions never page - ter_h and ter_o read a resident tile in place and any other through the file scratch (heights and now the photograph, four tiles each, sized when the tiles open, forgotten when they close), so terrain_height, _smooth, terrain_ortho, the chunk heightfields, ground_fill, grass, water and shadow no longer take slots or move the clock. Only the loaders page: tp_fill reads through tt_h_load / tt_n_load / tt_o_load, and terrain_tiles_prefetch as before. terrain_height_file is now terrain_height, kept as the name callers wrote against. No answer changes: every read was already the whole copy's texel. tests/height_file_test: heights and photograph equal the texels written, resident or not; a whole-map sweep of the questions, and a ground layer's fill over the map (a one-layer LGD2 written in the test), leave the slots, their contents, the clock and the read counts unchanged
