What the game makes as it runs no longer lies loose beside it: the shader
and pipeline caches (several GB, made for this build and this GPU) and
the button prompts made from the player's controls go in the game
folder's cache/, which can be deleted, and the logs in its logs/. The
Vulkan pipeline cache takes Longshot's name, longshot_vk_pipelines*.bin
(mkw-recomp's mkw_vk_pipelines* before).

host/game_layout.c makes both folders at the very start of both mains,
before a --prepare-shaders run too, and moves once what a build from
before left loose: renames in the same folder, never over a file there
(the log names one that stays), the pipeline cache renamed with its
stamp and play files, its cut-short writes and the old prompts deleted.
The build's files, the settings and the saves stay where they are.

The renderer finds them by gpu/vk/vk_paths.h's cache_path and log_path;
the shipped pipeline state list and the shader seed stay beside the
game. make_game.py seeds the pipeline list into cache/, the bug report
and the pipeline share read logs/ and cache/, dev_packs follows, and the
docs say where the caches and logs are.
