The result gauge stepped in 87 engine units of 8.4 px, so the fill crept
across the 50-cell / 21 px groove instead of lighting one cell at a time.
Convert the fill target to cells (points * 50 / max, floored like the game
HUD), step one cell per 7 frames (kGageSpeed_), place the norma at cell
30 / 35 / 40, and give the fill pieces the HUD's one-cell-wide art on the
groove's grid.
