render3d: scratch the frame uses is made with the state, not on first use

Browse source 
Render3dState's cam_planes, gpu_u_tmp, q_scratch, ov_nine_buf, the caster test's four points,
ter_bw, ter_scr and water_saved default to their buffers (as ludic.anim's clip state does), so the
lazy starts in cam_planes_update, gpu_tmp, terrain_height_smooth, ter_scratch, the water pass and
gvk_startup_state go. q_euler makes its views of q_scratch once (guarded on the view now). Compiled.
