-- add indication when CP is taken: in 1st man view it may be unclear if CP was

+- maybe remove setting string from menu (like music: 1) and use popups instead
+  (have just music and show "on" or "off" in popup)
 - on 1st map the camera is obscured by the wall at the start, fix it somehow
   (not the best first impression)
 - culling is very slow now, it showed that distance bailout can accelerate it

 - maybe each map could have a target time embedded: when beaten, the map would
   be marked as such
 - player name (modifiable via resource file)
-- popup messages? would be useful for several things: showing checkpoint times,
-  showing changes in menu etc.
 - make the racing module usable by itself, e.g. to allow making tools for
   verifying replays etc., i.e. make the module measure time, count checkpoints
   etc.

 - allow stopping car rotation in air like in Trackmania
 - countdown and finish text sometimes seem to jump horizontally somehow
 - add argc/argv to gameInit? could be used to quickly start maps, verify
