+- camera bugs in TCC build, also the auto test fails on checking rendered
+  pixels -- this may be TCC not supporting C99 fully? but dig up what's going
+  on
 - camera follow speed depends on FPS, it's slower with low FPS, but this is no
   big deal, it's only noticable with extremely high/low FPS -- fix or not?
 - replay loading BUG! somehow map2 replay was saves with hash 05ef0ab1 instead

 - mods:
   - bouncy car body with inertia, not affecting physics ofc, just eye candy
-  - TAS mod? ideas:
-    - step by single frames, the mod will literally keep all inputs in RAM, will
-      be able to rewind back (quickly replay the inputs)
+  - advanced replay analyzer, showing e.g.: distance travelled, speed over time,
+    crashes, input stats (number of presses, quickest tap, ...)
+  - TAS mod(s)? ideas:
+    - Just make it so that restarting takes player only N physics ticks back
+      (N can be a setting). Then the player can just drive and attempt sections
+      one by one, possibly in slow motion (using the existing setting).
+      Implement by literally storing exact inputs in RAM, then upon restart
+      quickly replaying everything up to current frame minus N.
     - kinda bruteforce solver?
     - export maps as 3D models in OBJ format (just print to console?)
-  - mod allowing to view two replays at once (one normal replay, one ghost),
-    would be cool for run comparison

   - some extra graphic consoomer goodies? like:
     - leave light trail behind the car (particles?)
     - postproc effects? render to a buffer in renderer, then draw it again
+    - something like a motion blur by kinda "frameless" rendering?
   - analog controller support, would just tap arrows in frequency according to
     analog the analog value; create a new frontend function to implement,
     something like LCR_getAnalogInput(type) or smt

     them swing, maybe even add delay to inputs
   - weather mods? like lightning (invert colors quickly), rain, snow, sand, ...
 - "AI" driver?
+  - could work like this:
+    - make a function that estimated "how well we are doing", i.e. how close
+      we are to finishing, taking into account number of taken CPs, distance
+      to closest CP, current speed etc.
+    - approx algorithm: maintain N "currently best drivers", in each iteration
+      let each of them drive N times randomly, i.e. we get N * N new drivers,
+      then pick N best of them (by the function) and repeat; if not making
+      any progress for some time we can recursively get back or something
 - 2D renderer? like isometric or top-down or something, could enable the game
   literally on very weak devices? top down might be nice, the car could be
   drawn out of circles, getting bigger closer to camera, camera could rotate
   along with car etc.
 - kinda fancy OpenGL renderer?
 - literal network multiplayer? could even be easy bcz no collisions
+  - map restarts should be synchronized to make the players start
+    simultaneously, this can be done by having a global shared timer ticking and
+    releasing all cars waiting for start every 3 seconds let's say
 - "user friendly" map editor?
 - procedural map generator?

+- LCR_SETTING_TEXTURE_SUBSAMPLE = 0 should turn off texturing completely

 - stop playing engine sound when replay finishes
 - add (digital) controller support to SDL and CSFML? NOT NOW, doesn't wanna
