Renamed BevPoint's members
* x,y,z -> vec[3]; compatible with other functions.
* f1 -> split_tag; used by displist to set the splitting flag.
* f2 -> dupe_tag; used in curve.c to remove duplicates.
BevList
* flag -> dupe_nr; was being used as a counter for duplicate points.
* use arithb.c functions where possible.
* arrays for coords, tilt and radius were being allocated, then copied into the BevPoint's, now write directly into the values without allocing/freeing arrays.

details...
- open curves use the first points orientation and minimize twist for each new segment.
- cyclic curves calculate the least twist in both directions and blend between them
- AxisAngleToQuat replaced inline code.
- Notice the model on the right now has more even corners. added Vec3ToTangent to arithb.c.
* extract_pose_from_pose only checked one of the list items for NULL when looping over them yet its possible they are different sizes.
* game_free_pose needed to be used rather then MEM_freeN, channels would never be freed leaking memory.
* setChannel() would make a new pose that wasnt aligned with the existing pose, the lists are assumed aligned so when extracting the channels its unlikely this was ever useful.
* Added getChannel() - returns pose loc/size/quat
* Added option args for setChannel(channel, matrix) or setChannel(channel, loc, size, quat)
actually two modifier datamask optimizations that were never done.
* Don't use modifier data mask for disabled modifiers.
* Check if UV data is needed for particle system instead of always
requesting it.
Big proxy fix (addressing hopefully most complaints on mailing list and
in tracker)
* proxy render settings are now independent of render size settings.
That means: which proxy size is used, is controlled by two parameters
now: the proxy size of the files, can be controlled with additional
buttons within the proxy panels. What is shown in a specific preview
window depends on the header settings of the preview panel.
So: proxies are _only_ used in those windows, that are switched to a
specific proxy resolution.
* output rendering is always done _without_ proxies.
* proxy generation now shows a waitcursor with numbers.
(closing Bug: [#18909] Building Proxies doesn't give any feedback
which was rather a feature request, since the problem mentioned there
was always the case :) )

You'll notice in the code the var is actually set again
a few lines down before being used so better to set it
after you've made sure the pointer is valid.

- Removed/Commented some unused vars
- CValue::GetPropertyText() could return a temp reference to a variable on the stack, option wasnt used anywhere so removed.
- KX_ConstraintWrapper::GetConstraintId allows args but ignored them
- KX_ConstraintWrapper::PySetParam didnt return NULL on an error (messing up pythons exceptions).
- BLI_natstrcmp didnt return 0 when the while loop exited
+ fixed Python method, PyArg_ParseTuple already checks for errors, no returning of NULL, thanks Campbell too)
+ added linear/angular spring for each of the 6DOFs of a generic 6dof constraint. This makes the generic 6dof constraint very versatile.

(todo: expose this setting in World setting GUI)
Expose contact processing threshold in Advanced GUI, next to rigid body margin, called CPT.
Default to 1, makes rigid body stacking a bit more stable, smaller values makes sliding easier (at the cost of easier jittering).
Disabled for 'dynamic' objects that don't rotate, because characters etc. always need smooth sliding.
Four new buttons in World settings to control frame rate:
fps: Nominal frame rate in frame per second.
Also sets the physics timestep = 1/fps
phys: Maximum number of physics timestep per game frame in case
the actual fps is less than nominal. This allows the
physics to keep up with real time even if the graphics slows
down the game.
sub: Fixed number of simulation substeps per physic timestep.
Improves the precision of the physics simulation. Useful for
fast moving objects for example.
log: Maximum number of logic steps per game frame in case the
actual fps is less than nominal. This allows the logic
system to follow the physics simulation.
Upper bound = phys
(setting the value higher than phys has no effect).
On games with heavy logic system, it is useful to set this
value to 1, to keep logic time under control.
All these values were already accessible from Python except phys:
GameLogic.getMaxPhysicsFrame():
Gets the maximum number of physics frame per render frame.
GameLogic.setMaxPhysicsFrame(phys):
Sets the maximum number of physics timestep that are executed per render frame.
Higher value allows physics to keep up with realtime even if graphics slows down the game.
Physics timestep is fixed and equal to 1/tickrate (see setLogicTicRate)
maxphysics/ticrate is the maximum delay of the renderer that physics can compensate.
phys: integer
Compound shape control
======================
1) GUI control
It is now possible to control which child shape is added to
a parent compound shape in the Physics buttons. The "Compound"
shape button becomes "Add to parent" on child objects and
determines whether the child shape is to be added to the top
parent compound shape when the game is stated.
Notes: * "Compound" is only available to top parent objects
(objects without parent).
* Nesting of compound shape is not possible: a child
object with "Add to parent" button set will be added
to the top parent compound shape, regardless of its
position in the parent-child hierarchy and even if its
immediate parent doesn't have the "Add to parent" button set.
2) runtime control
It is now possible to control the compound shape at runtime:
The SetParent actuator has a new "Compound" button that indicates
whether the object shape should be added to the compound shape
of the parent object, provided the parent has a compound shape
of course. If not, the object retain it's individual state
while parented.
Similarly, the KX_GameObject.setParent() python function has
a new compound parameter.
Notes: * When an object is dynamically added to a compound
shape, it looses temporarily all its physics capability
to the benefit of the parent: it cannot register collisions
and the characteristics of its shape are lost (ghost, sensor,
dynamic, etc.).
* Nested compound shape is not supported: if the object
being parented is already a compound shape, it is not
added to the compound parent (as if the Compound option
was not set in the actuator or the setParent function).
* To ensure compatibility with old blend files, the Blender
subversion is changed to 2.48.5 and the old blend files
are automatically converted to match the old behavior:
all children of a Compound object will have the "Add to
parent" button set automatically.
Child ghost control
===================
It is now possible to control if an object should becomes ghost
or solid when parented. This is only applicable if the object
is not added to the parent compound shape (see above).
A new "Ghost" button is available on the SetParent actuator to
that effect. Similarly the KX_GameObject.setParent() python function
has a new compound parameter.
Notes: * This option is not applicable to sensor objects: they stay
ghost all the time.
* Make sure the child object does not enter in collision with
the parent shape when the Ghost option if off and the parent is
dynamic: the collision creates a reaction force but the parent
cannot escape the child, so the force builds up and produces
eratic movements.
* The collision capability of an ordinary object (dynamic or static)
is limited when it is parented: it becomes automatically static
and can only detect dynamic and sensor objects.
* A sensor object retain its full collision capability when parented:
it can detect static and dynamic object.
Python control
==============
KX_GameObject.setParent(parent,compound,ghost):
Sets this object's parent.
Control the shape status with the optional compound and ghost parameters:
compound=1: the object shape should be added to the parent compound shape (default)
compound=0: the object should keep its individual shape.
In that case you can control if it should be ghost or not:
ghost=1 if the object should be made ghost while parented (default)
ghost=0 if the object should be solid while parented
Note: if the object type is sensor, it stays ghost regardless of ghost parameter
parent: KX_GameObject reference or string (object name w/o OB prefix)
Servo control motion actuator did not work as expected when the object
is moving on a moving platform.
This patch introduces a new Ref field in the servo motion actuator
to set a reference object for the velocity calculation.
You can set the object during the game using the actuator "reference"
attribute; use an object name or an object reference.
The servo controller takes into account the angular velocity of the
reference object to compute the relative local velocity.
- Size adjustments can be accomplished with warp mesh data now. So we get a free spot in the GUI for a tilt option.
- Tilt option to tilt the camera (for planetarium domes).
Angle is in degree from -180 to +180. It's needed for planetarium domes (as this one http://domejunky.blogspot.com/2009/05/dome-corrected-bge.html ).
- This is the last commit regarding dome code I expected to 2.49. I consider this feature full implemented now. (working on docs now)
Particles using group-duplication, with Metaballs in group, enter eternal
loop in our code now. This is a non-supported case... metaball code doesn't
support recursions. Added a provision in code to catch this case, and print
an error in console to denote this.
fix this by freeing the lib-file-data after linking or appending, re-appending will be slower now
(as slow as appending for the first time).
Not strictly needed, set the memory for bhead's to zero in readfile.c since comparisons are done later on with this data making valgrind complain.
Added some missing headers too.
Blender crashed, when started in debug -d, with compositor, after render.
Reason was the BKE_image_print_memlist() which reads the ibuf->rect from
all images, but for Image types "VIEWER" that's not valid, this data is
coming from other sources.
