Orkuncakilkaya eee6a0906e render3d: the ground's maps read through a page table of fine tiles over a coarse map (shaders) ...

terpage.glsl is the reference block (tpSlot, tpUV, terHeight, terHeightSmooth, terNormalXZ,
terOrtho, tpOrthoRes, tpOrthoLod), pasted by section into terrain.vert, terrain.frag,
tersun.frag, model.vert, grass.vert and grass.mesh. u_tp_on = 0 reads the old samplers with the
old coordinates and filtering; on, a resident tile is read at level 0 from u_tp_h / u_tp_nrm /
u_tp_ortho, anything else from the coarse map now bound under the old names. The B-splines use
the FULL map's texel and take every tap through the page, so a tile edge stays one surface;
blurred photograph reads (lod 1-2.5) stay on u_ortho with the level moved down by the coarse
map's ratio. The fragment stages drop their unused u_height. SPIR-V rebuilt: terrain programs
carry 23 samplers (21 in the fragment stage), up from 19.
