The collab backdrops (and the default donbg band) replay exported movies
whose per-frame channels were Lua tables of numbers: 38 MB that Lua
compiled on every song start (0.7 s for the TOHO pack; game screen init
1.5-1.6 s -> 0.9-1.0 s in-game), plus ~19 MB of Lua memory per pack.
Each per-frame array is now {base, step, width, "digits"}: value = base +
step * n, n being the frame's width chars in base 92 (printable ASCII
without '"' and '\'). One string constant compiles in a fraction of the
time; bg_objects/packed_channel.lua decodes the frame being drawn.
Quantization: 0.05 px, 0.005 deg, 5e-5 scale, 1/1024 alpha and tint;
every value of all 77 files checked against the original within half a
step.
