hiker 92aec928a1 Tweaked physics so that wheel raycasts happen from inside the collision shape 
(fixes karts getting stuck at borders), use a longer less bevelled collision
shape better kart stability), and reduce angular factor to make it less
likely that karts can drive on walls.

smooth-angle-limits: If the angle between the normal of a vertex and

has the effect of an edge split modifier - if the flat track and (say)
a wall at a 90 egree angle are not separated, the normal at that
vertex will be 45 degrees, resulting in completely wrong physics.
The angle limit in this case will discard the 45 degrees, and use
the normal of the flat triangle (pointing upwards). In the worst
case (all three normals discarded, the interpolation will just
return the normal of the triangle (i.e. de facto no interpolation),

<!-- Default values for all karts
============================ -->
<general-kart-defaults>
<!-- Skidding: increase: multiplicative increase of skidding factor in each frame.
decrease: multiplicative decrease of skidding factor in each frame.
max: maximum skidding factor = maximum increase of steering angle.
time-till-max: Time till maximum skidding is reached.
visual: Additional graphical rotation of kart. The graphical rotation
of the kart also determines the direction the kart is driving to
when skidding is stopped.
visual-time: How long it takes for the visual skid to reach maximum.
revert-visual-time: how long it takes when stopping a skid to revert
the visual skid and bring visuals and physics in sync again.
angular-velocity: Angular velocity to be used for the kart when skidding.
min-speed: Minimum speed a kart must have before it can skid. Must be
>0, otherwise the kart can skid at the start of the race.
time-till-bonus: How long a kart needs to skid in order to get a bonus.
bonus-force: A speedup applied to the kart whick skidded for a while.
bonus-time: How long the bonus-force is applied.
bonus-force: Additional engine force (this is used to offset the fact
that turning after skidding (e.g. to correct direction) often uses
up the skid bonus).
post-skid-rotate-factor: a factor to be used to determine how much
the chassis of a kart should rotate to match the graphical view.
A factor of 1 is identical, a smaller factor will rotate the kart
less (which might feel better).
physical-jump-time: Time for a physical jump at the beginning of a skid.
graphical-jump-time: Time for a graphics-only jump at the beginning
of a skid.
reduce-turn-min/max: The steering done by the controller (which is in
[-1,1]) is mapped to [reduce-turn-min, reduce-turn-max] when skidding
is active (for left turn, right turn will use [-max, -min]). The
effect is that while you skid (say left) you can adjust the direction
of the turn the kart is doing somewhat by steering to the left and right,
but you will always keep on doing a left turn, just more or less. -->
<!-- Kart-specific settings used by the AI.
use-slipstream: if the AI should try to overtake karts using slipstream.
disable-slipstream-usage: even if the AI is not trying to use slipstream,
it can get a lot of bonus, esp. on easy since the AI creates trains.
Set this to true to make sure AI does not get any slipstream bonus.
shield-incoming-radius: Radius at which projectiles will be detected and
trigger a shield usage.
false-start-probability: Probability of a false start.
min/max-start-delay: Minimum and maximum start delay.
See http://www.humanbenchmark.com/tests/reactiontime/stats.php
Average reaction time is around 0.215 s.
nitro-usage: "none", "some", "all": if nitro should be used, and
how much the AI should try to use it good.
non-random-item-usage: If true, use items in a sophisticated way,
otherwise use items randomly.
collect-avoid-items: if the AI should collect and avoid items,
or just ignore them.
handle-bomb: If the AI should actively try to pass on a bomb.
skidding-threshold: only for old-style skidding: when sharp turn
should be triggered. Smaller values means it will sharp turn
earlier, resulting in better driving in thight curves.
max-item-angle: Items that would need more than this change in
direction are not considered for collection.
time-full-steer is the time for the AI to go from neutral steering to
extreme left (or right). This can be used to reduce
'shaking' of AI karts caused by changing steering direction
too often. It also helps with making it easier to push the
AI karts (otherwise micro-corrections make this nearly
impossible). A value of 1/maxFPS / 2 will guarantee that
the wheel can go from -1 to +1 steering in one frame,
basically disabling this mechanism.
bad-item-closeness is the maximum distance between a good and a
bad item which can force the AI to abandon a good item in order
to avoid hitting a bad item. If the distance is larger, it is
assumed that there will be enough time to change steering
direction.
straight-length-for-zipper is the minimum length a straight
section of the track should have in order to activate a zipper.
competitive when ahead of the player, or more competitive
when behind the player.
skid-probability: Since the AI is usually very good at using
skidding, this is used to implement some rubber-banding for
the AI: depending on distance to the player, the AI will
change the probability of skidding. This attributes takes
a space-separated list of "distance:probability" pairs
(negative distances meaning the kart is behind the player,
a positive number that the AI is ahead of the player).
Then list should have at least 2 entries. Depending on
the actualy distance the kart has the probability is then
linearly interpolated (if the AI is more than the largest
distance ahead, the value for the largest distance is used,
and similarly if the kart is more than the minimum value
behind).
speed-cap: Fraction of maximum speed the kart should drive
at. Used to slow down karts that are ahead of the player.
Note that setting this to a value >1 does NOT increase
the speed the kart can drive at!
collect-item-probability: Probability of the AI actually
trying to collect an item (if an item is selected for
collection in the first place).

<!-- collision
impulse-type: STK can apply an additional impulse in case of
kart-track collision:
'none' : no additional impulse
'normal': impulse along the normal
'driveline': impulse towards the nearest driveline.
An impulse towards the driveline works nice when the kart is
driving more or less correctly on the track - it pushes the
kart in the right direction. But if the kart is significanlty
off track, it has severe problems (since an incorrect
driveline point can be selected, pusing the kart in the
wrong direction, sometimes even causing a 'zip-along-obstacle'
effect.
impulse: an additional impulse to be applied in a non-frontal
collision to push two karts away from each other.
impulse-time: The impulse will be applied over a certain time
period, which results in less abrupt changes. If set to 0,
the impulse is only applied once.
resitution: restitution value to be used for the kart rigid bodies.
bevel-factor: for each point of the chassis collision box one
additional point is added, resulting in a bevelled box shape.
The original Z coordinate of the chassis is multiplied by
1-bevelZ (i.e. the main box part of the shape is shortened).
The bevel point has the original Z coordinate, and the X and
Y coordinates of the box are multiplied with (1-bevelX) and
(1-bevelY). A value of 0 for all bevel coordinates disables
bevelling, and uses a simple box shape.
As an example, a value of 1 for x and z will result in a
sharp 'arrow' like shape.
physical-wheel-position: Defines where the 'physical' (raycast)
wheel will be located. It's a weight factor with 0 = being
at the widest side of the bevel, 1 = at the front and
narrowest part of the kart. If the value is less than 0, the old
physics settings are used which places the raycast wheels
outside of the chassis and results in more stable physical
behaviour of the karts. -->
