This will be used for calculating bezier curves from freehand drawing,
may be used for other areas too.
Original code from GraphicsGems, 1990 (FitCurve.c),
with updates from OpenToonz, under 3 clause BSD license.
with own minor modifications for integration with Blender:
- support adding extra custom-data.
- improved handle clamping.
This patch adds a python method to get openGL bind code of material's texture according to the texture slot.
Example:
import bge
cont = bge.logic.getCurrentController()
own = cont.owner
bindId = own.meshes[0].materials[0].getTextureBindcode(0)
Test file: http://www.pasteall.org/blend/40679
This can be used to play with texture in openGL, for example, remove mipmap on the texture or play with all wrapping or filtering options.
And this can be used to learn openGL with Blender.

While SCons building system was serving us really good for ages it's no longer
having much attention by the developers and started to become quite a difficult
task to maintain.
What's even worse -- there started to be quite serious divergence between SCons
and CMake which was only accumulating over the releases now. The fact that none
of the active developers are really using SCons and that our main studio is also
using CMake spotting bugs in the SCons builds became quite a difficult task and
we aren't always spotting them in time.
Meanwhile CMake became really mature building system which is available on every
platform we support and arguably it's also easier and more robust to use.
This commit includes:
- Removal of actual SCons building system
- Removal of SCons git submodule
- Removal of documentation which is stored in the sources and covers SCons
- Tweaks to the buildbot master to stop using SCons submodule
(this change requires deploying to the server)
- Tweaks to the install dependencies script to skip installing or mentioning
SCons building system
- Tweaks to various helper scripts to avoid mention of SCons folders/files
as well

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).
Rationale are described more precisely in the thread

I have removed the m_pHitObject, m_xray and m_testPropName and replace them by a temporary struct "RayCastData" which contains these datas and a collision mask. Finally i add a collision mask argument in the python function "rayCast" :
```
rayCast(to, from, dist, prop, face, xray, poly, mask)
```
It can be useful to hit only object which are on the right colision layer. for example if you have hitbox for a charater or vehicle you don't want to hit it with raycast.

Mostly added missing :arg: clauses -- these caused the :type:-clauses
that were already in the RST files to be hidden from the output HTML.
I also fixed some argument types from 'list' to 'Vector' where applicable
and corrected some obvious mistakes.
- add missing uniforms.
- add uniform types.
- link to RNA equivalent.
- remove 'value' from uniforms (they were wrong, better use module members anyway).
- various corrections & edits.

The documentation for bge.render.{setWindowSize,setFullScreen,getFullScreen}
did not mention that those functions are no-ops when using the Blender-
embedded player.
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.

It works similar to getActionFrame(), you have to give a layer or not (for layer 0) as the argument and it returns the name of the animation that the object is currently playing.
Example:
```
import bge
own = bge.logic.getCurrentController().owner
own.playAction("SomeAction",0,20)
print(own.getActionName())
```
>> SomeAction
Here is an example file, just open the blend file with the terminal opened
and press P, you can see how the current animation is being printed:
