The game's five camera sensitivities (Options, Very Low to Very High) turn the camera at the rates
in the StickSensitivity array of PlayerCamera.game__component__PlayerCameraParam.bgyml, 0.8 to 2.4.
stick_sens (0.1 to 3, read at start) multiplies that array: camera_speed.c decompresses
Pack/Actor/PlayerCamera.pack.zs with the RomFS's pack.zsdic, scales the floats in place and
compresses it again with the same dictionary, and romfs.c serves the result from
<profile>/camera/. Scaling the stick's deflection instead could not raise the top speed, since a
full tilt cannot go further.
The mouse camera reaches the game as a right-stick deflection, so input_win.c mouse_camera divides
it by the same factor and mouse_sens alone keeps setting the mouse's speed.
romfs.c heapdef_overlay is split into read_served and serve_generated so both generated files
share the reading, writing and overlay bookkeeping.
