Builds a browser-playable .html/.js/.wasm/.data via `./build-web.sh` (no
new CMake top-level target — Emscripten is detected at configure time and
takes the existing kobodl through a web-flavored pipeline).
Key pieces:
- CMakeLists.txt: route SDL3 through `--use-port=sdl3`; substitute
`--use-port=libpng` for the missing sdl3_image port (Emscripten 5.0.7
ships only sdl3 + sdl3_ttf). pthread (atomics+bulk-memory) lifted to
kobo_deps so every TU agrees with wasm-ld's --shared-memory. Link with
-sASYNCIFY (avoids rewriting kobo's blocking main loop around
emscripten_set_main_loop), -sALLOW_MEMORY_GROWTH/-sMAXIMUM_MEMORY=1gb,
-sPTHREAD_POOL_SIZE=4, -lidbfs.js, and --preload-file data@/data.
- graphics/img_compat.{h,c}: libpng-backed IMG_Load shim, used in
sprite.c / gfxengine.cpp / filters.c via #include "img_compat.h".
Native builds passthrough to <SDL3_image/SDL_image.h> unchanged.
- web/shell.html: HTML wrapper that mounts /home as IDBFS for persistent
scores/config. Startup gated on addRunDependency until syncfs(true)
finishes, then /home/scores is mkdir'd post-load (the game's addPlayer
doesn't auto-create the score dir; see TODO in score.cpp).
beforeunload + visibilitychange flushes /home back to IndexedDB.
- build-web.sh: emcmake wrapper + a static server that sets the
COOP/COEP headers SharedArrayBuffer/pthreads require.
Source fixes needed to build under Emscripten's libc/libcxx:
- Renamed enemy_kind `pipe2` -> `pipe2k` (collided with libc pipe2(2)
always declared in Emscripten's <unistd.h>).
- graphics/toolkit.cpp: added missing <stdio.h> for snprintf (Emscripten's
libcxx headers don't pull it in transitively).
- states.cpp: gated the "Quit Kobo Deluxe" main-menu button on
!__EMSCRIPTEN__; exit() on the web leaves a dead canvas.

When KOBO_BENCH=1 is set in the environment, the game becomes a
hands-off benchmark:
* Skips the intro/menu sequence and pushes st_game directly with
scene=0, skill=CLASSIC, invulnerable ship, always_fire = constant
auto-fire, countdown = 0 so "GET READY" auto-pops in 700ms.
* Seeds pubrand and gamerand from KOBO_BENCH_SEED (default 12345)
so the map, stress spawn pattern, and enemy AI are identical
run-to-run.
* Defaults KOBO_STRESS=1500 unless overridden, so the move pass has
a steady workload, and KOBO_PROF=1 so the profiler is on.
* Counts frames in run_game; after KOBO_BENCH_FRAMES (default 1800)
it dumps prof to stderr and exits cleanly.
Usage from repo root (the cwd matters — relative GFX paths only
resolve from here):
KOBO_BENCH=1 ./build/kobodl 2>bench-logs/phaseN.log
A single command produces a comparable profiler dump at every phase
of the DOD refactor — no menus to navigate, no keyboard input,
identical workload.

Adds a tiny zone-based profiler (prof.{h,cpp}) enabled via KOBO_PROF=1.
Instruments run_game with zones for myship.move, enemies.move (split into
realize and move_pass), hit_structure, and hit_bolt. Adds KOBO_STRESS=N
to keep the enemy pool topped up with rocks for stable per-frame timing.
Why: the entity/render pipeline refactor in BENCH.md needs a comparable
baseline before any layout changes. Without a stress workload the natural
gameplay enemy count is too noisy to compare across commits.

This is the first commit of the SDL 1.2 -> SDL 3 migration. It lands
the build-system change and the include-path rewrites; the code does
NOT compile against SDL 3 yet, by design. Stays on this branch until
the migration is finished.
- CMakeLists.txt: find_package(SDL3 CONFIG) + SDL3::SDL3 /
SDL3_image::SDL3_image. Drops the legacy FindSDL machinery.
- glSDL.h, sprite.c, glSDL.c, filters.c, gfxengine.cpp, audio.c:
rewrite #include "SDL*.h" -> <SDL3/...> / <SDL3_image/...>.
Known wall: graphics/glSDL.{c,h} collides with SDL 3's surface API
renames (SDL_FreeSurface, SDL_FillRect, SDL_SetColorKey,
SDL_SetClipRect, SDL_bool). The next phase deletes the entire glSDL
shim and rewrites graphics/ against SDL_Renderer / SDL_Texture.

Replace configure.in + 7 Makefile.am files with a CMake build:
- Top-level CMakeLists.txt with feature detection (SDL 1.2,
SDL_image, OpenGL, optional OSS/ALSA), platform-specific install
layouts (macOS .app bundle, Windows simple bundle, Unix), and a
shared kobo_deps INTERFACE target for flags and link libraries.
- Sub-CMakeLists for graphics/, sound/, eel/ static libraries.
- aconfig.h.cmake.in and Info.plist.cmake.in templates (minimal:
only the HAVE_* macros actually referenced by the code).
Remove all autotools machinery: configure, configure.in, aclocal.m4,
Makefile.am files, generated Makefile.in files, install-sh, missing,
depcomp, compile, mkinstalldirs, config.guess, config.sub, the
buildpkg.sh Solaris helper, and the cfg-* configure shortcuts.
Update .gitignore for CMake out-of-tree builds, and point
run-kobodl.sh at build/kobodl (overridable via KOBODL_BIN).
