This function allows the user to run specific code for each of the
rendered stereoscopic eyes in the Game Engine.
The initial use case is to set the camera projection matrix in
a scene.pre_draw callback function for each eye, to be used in VR
(Virtual Reality) installations.

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.

Instead of getting fancy this time, we'll just use Mahalin's simpler
fix. This may have slight performance impacts, but it is a lot simpler
than the previous fix and shouldn't cause as many bugs.
With this fix the mouse actuator movement works well as with even screen resolutions as odd screen resolutions.
Also it fixed the movement when the border of the blenderplayer window is out of the screen limits.

remove 'type' argument, very few mathutils objects are wrapped,
add new function for creating wrapped objects.
also fixes unlikely memory leak if the data-array can't be allocated.
Navigation mesh object need to access the current scene at
creation time. This can be at scene start or when an object
is instantiated from an inactive layer. The method of getting
the scene differs in these cases. This fix handles both.
Scene replacement with invalid scene name was crashing blender,
now it's a no-op.
KS_Scene.replace() to return a boolean to indicate if the scene
is valid and is scheduled for replacement. This allows more
robust game management.
1. This patch fix the KX_ConstraintWrapper documentation (radian instead of degrees).
2. It also adds the missing GENERIC_6DOF_CONSTRAINT constant.

This is related to Task T34861 to increase up & track axis options for TrackTo actuator. I've just added it to differential to facilitate an easier review.
With the patch applied you can select X, Y and Z axis for the Up axis, and X, Y, Z, -X, -Y and -Z for the track axis.
Related to the implementation I have used the algorithm from Trackto constrain placed in constrain.c but adapted to be used with MOTO library.
The wiki docs are here (http://wiki.blender.org/index.php/User:Lordloki/Doc:2.6/Manual/Game_Engine/Logic/Actuators/Edit_Object#Trackto_Actuator).
Test file is here: {F97623}
I have also uploaded 2 screenshots showing the UI modifications to the TrackTo actuator:

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.
This is related to task T29419. Credit also goes to Goran Milovanovic
(goran) for proposing an initial fix for this issue.
The issue is the current behavior of applyImpulse doesn't match the behavior
described in the documentation as instead of a impulse point in world coordinates,
it seems to require a coordinate in a local space.
Additionally, applyImpulse function isn't consistent with similar functions (applyForce, applyTorque, etc)
as it doesn't allow to choose in which space (local or global) the impulse is applied.
Now, we have the following function:
applyImpulse(point, impulse, local=False)
being "point" the point to apply the impulse to (in world or local coordinates). When local is False will
have both point and impulse in World space and when local is True will have point and impulse in local space.

Disclaimer: The author of this patch is Geoffrey Gollmer (gomer). I only updated the patch to the current git master status, reworked several parts to fit well with current coding style and applied several fixes.
This actuator allows users to show/hide the mouse cursor using logic bricks, as well as control object rotation with a mouse in the BGE.
The mouse rotation is flexible enough to allow any type of mouse look, as well as banking for flight controls.

Using layer visibility in active render layer makes more accurate

GLSL lamps now ignore layer visibility if lock_camera_and_layers is
OFF or game engine is running. The material lamp group still works
unconditionally though.
