render3d: start-up declared, ov_nine and the caster test on buffers made once - 362 frame sites to 122

Browse source 
The renderer starts itself from the first frame (gpu_select), so the device, its tables, the
manifest and programs, grass, shadows, sky, terrain textures and the actor pool read as frame
allocations: each is @alloc_ok as start-up, with gvk_fail (a failure) and the actor census and
texture dump (debug switches). ov_nine's four corner/uv arrays are one floats(16) made in
gvk_startup_state; ac_in_light's four points are made there too. Compiled (steady, and ludic deps
over main 4316ff97).
