This patch improves clock management in BGE, to be able to accelerate /
slow the time, and also to finely synchronize clock with external
engines. Several new python functions have been added and existence ones
have been improved for that purpose. Now we have:
- getClockTime(): Get the current BGE render time, in seconds. The BGE
render time is the simulation time corresponding to the next scene that
will be rendered.
- getFrameTime(): Get the current BGE frame time, in seconds. The BGE
frame time is the simulation time corresponding to the current call of
the logic system. Generally speaking, it is what the user is interested
in.
- getRealTime(): Get the number of real (system-clock) seconds elapsed
since the beginning of the simulation.
- getTimeScale(): Get the time multiplier between real-time and
simulation time. The default value is 1.0. A value greater than 1.0
means that the simulation is going faster than real-time, a value lower
than 1.0 means that the simulation is going slower than real-time.
- setTimeScale(time_scale): Set the time multiplier between real-time
and simulation time. A value greater than 1.0 means that the simulation
is going faster than real-time, a value lower than 1.0 means that the
simulation is going slower than real-time. Note that a too large value
may lead to some physics instabilities.
- getUseExternalClock(): Get if the BGE use the inner BGE clock, or rely
or on an external clock. The default is to use the inner BGE clock.
- setUseExternalClock(use_external_clock): Set if the BGE use the inner
BGE clock, or rely or on an external clock. If the user selects the use
of an external clock, he should call regularly the setClockTime method.
- setClockTime(new_time): Set the next value of the simulation clock. It
is preferable to use this method from a custom main function in python,
as calling it in the logic block can easily lead to a blocked system (if
the time does not advance enough to run at least the next logic step).

This class did nothing but print out extensions if they were found.
Instead, the code from bge.logic.PrintGLInfo() is now printed as the
Rasterizer is initialized. This gives better information, and it removes
some GL code from KX_PythonInit.cpp (the PrintGLInfo method now calls
the Rasterizer to print the information).

By using getAnimRecordFrame(), game developers have access to the frame
number used by the "Record animation" feature. This enables them to
record additional information in Blender's F-Curves and ensuring perfect
synchronization with the information already recorded by Blender.
The setAnimRecordFrame() can be used to change the frame number at which
animations are recorded, for example to introduce delays the recording that
do not require delays in the actual game/simulation run.
The getter/setter functions in KX_KetsjiEngine are not directly named after
property they access (m_currentFrame). I found "current frame" to be too
vague for a public interface, hence chose a more descriptive name.

All of the initXPythonBinding functions are changed to always creating the module instead of importing if previously existing.
I can instead only remove the module return when the import is ok, so that it always inits. But then, I don't see the point in importing.
I make sure that these functions are called only once per run, inside initBGE.
This was not the case with GameTypes. I moved initPyTypes inside of initGameTypesPythonBinding due to that.
I reorganized initGamePlayerPythonScripting and initGamePythonScripting so that they run things in the same order.
initGamePlayerPythonScripting imports mathutils and aud, the other only aud. Shouldn't it be the same for both?

Hilighted changes are:
- consistent naming and initialization of BGE submodules
- initialization of the 'bge' module as a proper module
- using PyDoc_STRVAR instead of static char*
- generic cleanup (unused arguments, logica ordering, naming and whitespace)

This function allows the user to run specific code for each of the

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

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.

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.

BGE Physics Cleanup: Removing GetReactionForce() since all implementations returned (0, 0, 0).

BGE Phsyics Cleanup: Making PHY_IController and its derived classes follow a consistent naming scheme for member functions. They now all start with capital letters (e.g., setWorldOrientation becomes SetWorldOrientation).
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().
This will make transitions from older versions of Blender easier since VSYNC_ON
will be the default. This could have been changed in a do_version, but the vsync
code has yet to see an official release, so I figured this would be a bit nicer.
Also, this makes VSYNC_ON the default for new scenes as well.
