This is a new KX_GameObject attribute that it increments the
possibilities of optimization during the game
Additionally the unused m_bSuspendDynamics variable is removed.

This change introduces a new hysteresis parameter that it will be added
or subtracted to/from the LOD distance to avoid popping when a LOD
object moves close to the LOD transition continuously.
Then, we have the following:
- a new LOD Hysteresis setting per scene (default 10%) which is located
in Scene context --> Level of Detail panel. This scene parameter also
will active/deactive the scene hysteresis.
- and a new LOD Hysteresis setting per object (default 10%) which is
located in Object context --> Levels of Detail panel. The LOD hysteresis
setting per object (if active) will overwrite the hysteresis setting per
scene value.
For the new blends: the hysteresis setting per scene would be active by
default and the per object would be inactive by default.
For the old blends: both hysteresis settings (per scene and per object)
would be inactive by default. A quick way to take advantage of this
feature for old blends would be to activate the hysteresis parameter in
the scene context -> Level of Detail panel

This patch will add a physics constraints replication for group instances
(dupli group).
It also fix crashing when when a group instance is made from a linked
group instance and both are on the active layer.

Added a new "current_lod_level" property to the python api of
KX_GameObject. The property returns the current lod level of the game
object. The purpose of the property is activate logic routines only when
an object is at a certain lod-distance from the camera, avoiding to
separately recomputing the same distance in the logic script. Usage in
python script might look like:
owner = bge.logic.getCurrentController().owner
lod_level = owner.currentLodLevel
if lod_level == 0: ...do something
else: ... object might be too distant

This patch adds two parameters to the functions in the
collisionCallbacks list. The callback function should thus be like
this:
```
def on_colliding(other, point, normal):
print("Colliding with %s at %s with normal %s" % (other, point, normal))
game_ob.collisionCallbacks.append(on_colliding)
```
The `point` parameter will contain the collision point in world
coordinates on the current object, and the `normal` contains the
surface normal at the collision point.
The callback functions are checked for the number of arguments
`co_argcount`. The new `point` and `normal` arguments are only passed
when `co_argcount > 1` or when `co_argcount` cannot be determined.

This patch adds the following R/W properties and method to `KX_GameObject`:
- `linearDamping` -- get/set linear damping
- `angluarDamping` -- get/set angular damping
- `setDamping(linear, angular)` -- set both simultaneously
These allow runtime changes to the same properties that are accessible at design time in Blender's UI via `game.damping` and `game.rotation_damping`. The names of the properties were chosen to mirror the internal names of the BGE physics engine, as these are (AFAIK) also the commonly used names in physics literature.

This is mostly the same fix as before, but now code depending on culling
checks is executed after KX_Scene->CalculateVisibleMeshes(). As a
side-effect, LoD checks and animation culling now use the current
frame's culling information rather than the previous frame's.
Updating object IPOs is not currently thread-safe since it also updates
children. This leads to problems when parents and children are both
animated. For now, updating object IPOs is done in its own loop to avoid
threading issues.
Levels of detail can be added and modified in the object panel. The object
panel also contains new tools for generating levels of detail, setting up
levels of detail based on object names (useful for importing), and
clearing an object's level of detail settings. This is meant as a game
engine feature, though the level of details settings can be previewed in
the viewport.

BGE Physics Cleanup: Getting rid of KX_GameObject::SuspendDynamics() and KX_GameObject::RestoreDynamics(). Instead, use the functions from the physics controller.
BGE: Some first steps in trying to cleanup the KX_IPhysicsController mess. KX_GameObject now has a GetPhysicsController() and a GetPhysicsController1(). The former returns a PHY_IPhysicsController* while the latter returns a KX_IPhysicsController. The goal is to get everything using GetPhysicsController() instead of GetPhysicsController1().
KX_GameObject now has a collisionCallbacks list which is a list of callables that are called when a collision occurs. The callables will be called with an argument that contains a reference to the other object involved in the collision (i.e., not self).
* KX_GameObject.member returns the list of group members if the object is a group object, otherwise None is returned
* KX_GameObject.group returns the group object that the object belongs to or None if the object is not part of a group
- spelling - turns out we had tessellation spelt wrong all over.
- use \directive for doxy (not @directive)
- remove BLI_sparsemap.h - was from bmesh merge IIRC but entire file commented and not used.

To be implemented after merge:
1) add pydocs(rst) for the video texture new defines
2) see if a NodeSetLocalMatrix would fit well
#43439 by kupoman
Changing the worldTransform and localTransform python attributes to use BLI_math to simplify the code
#38242 by kupoman
Adding the constants SOURCE_ERROR, SOURCE_EMPTY, SOURCE_READY, SOURCE_PLAYING, SOURCE_STOPPED to the video texture module. Updates to the documentation will follow after a merge with trunk
#38187 by kupoman
Updates to the documentation to reflect that worldScale is now writable, and added localTransform and worldTransform to KX_GameObject.
#38180 by kupoman
The Transform attribute of KX_GameObject was based on world space data. I converted that one to worldTransform, and added a localTransform for local space transform information.
#38179 by kupoman
Fixed the transform attribute of KX_GameObject's set method to properly deal with negative scaling.
#38177 by kupoman
Updated the transform property on KX_GameObject so that it is now read/write, and added the corresponding set method. Also simplified the get method by calling GetOpenGLMatrix instead of making the matrix myself.
#38167 by kupoman
Adding a read only transform attribute to KX_GameObject that returns a 4x4 matrix representing the object's transformations.
#38166 by kupoman
Adding a worldScale attribute to KX_GameObject. This attribute scales the object independently of its parent's scale.
* Blendin for Loop End works even after a negative pulse. Flipper could still use some work in this area.
* Continuous works a lot better.
* BL_Action::SetFrame() should work a little smoother.
* Adding methods KX_GameObject.stopAction() and KX_GameObject.isPlayingAction().
* Made all layer arguments optional. This means I had to change setActionFrame(layer, frame) to setActionFrame(frame, layer=0). This seems a little backwards to me, but I guess that's what you get with optional arguments. Also, this will break existing scripts.
* Made sure to check user supplied layer values on all action methods. Previously this was only done for playAction().
* Fixed a few newline issues.
