A prerequisite to create physics objects for statics was to remove the
dependency on base node (since it doesn't yet exists) for object
position. It is still necessary for animation though.
Restore the basenode (and the associated FIXME) so that animated objects works properly.
Since actors can be active in 3x3 grid around the player, we need to
first load all statics in a 5x5 grid around the player.
Split load and unloading in 2 phases. Add an mInactiveCells set into the
scene, which contains all cells inside the aforementioned 5x5 grid.
These cells contains only heightfields and physics objects of static
class.
loadCell always adds a height field, but unloadCell only removed it for
cells with height data. Reloading a cell overwrote the height field
added earlier (leading to its destruction) while the navigator retained
a reference to the now deleted collision shape, leading to a crash.
Always write opaque fragments instead of relying on blending being off for translucent RTT II: Daggerfall

imprecision issue with projectile collision detection.
Simplify the mechanics: manage hits in one spot.
Give magic projectiles a collision shape similar in size to their visible
model.
Rename the 2 convex result callback to clearly state their purpose.
In this case, the actor mPreviousPosition is not updated, so the actor
position is interpolated between an old (stucked) position and the new
(unstucked) position. The new position is most likely "stucked", so the
unstuck code strikes again, making the actor "vibrates".
That's exactly what the sync code path does, and it doesn't exhibit this
behavior.
The jump state initial state is "none", and it is set after physics simulation.
If a save is done just above the ground, the character may land before
the first run of the simulation, effectively cancelling the effect of
falling.
What happened is that the last handle to an Actor shared_ptr was a
promoted weak_ptr. When the shared_ptr goes out of scope, the Actor dtor
is invoked. That involves removing the Actor collision object after
exclusively locking mCollisionWorldMutex. In this case, the lock was
already held in the outter scope of the promoted weak_ptr.
Reduce the scope of the mCollisionWorldMutex to never encompass the
lifetime of a promoted weak_ptr.
