Clamp objects min/max velocity.
Accessed with bullet physics from the advanced button with dynamic and rigid body objects.
- useful for preventing unstable physics in cases where objects move too fast.
- can add linear velocity with the motion actuator to give smooth motion transitions, without moving too fast.
- minimum velocity means objects don't stop moving.
- python scripts can adjust these values speedup or throttle velocity in the existing direction.
Also made copy properties from an object with no properties work (in case you want to clear all props)

Re-enable vertex welding, only for soft bodies. They require it. Future versions could expose such vertexWeldingThreshold.

angular rotation). The setting broke 'dynamic'-only objects.

Was adding each face with a remove doubles option that made conversion increasingly slower for larger meshes, this would often hang blender when starting with the BGE with larger meshes.
Replace btTriangleMesh()->addTriangle() with btTriangleIndexVertexArray()
YoFrankie level_1_home.blend starts a third faster, level_nut about twice as fast.
- previous commit was also incorrect using the original meshes vert locations rather then the vert locations that came from the derived mesh.
- Softbody is relying on removing doubles at 0.01 to give stable results, this no longer works but seems a bit dodgy anyway. Maybe some post-processing filter could fix up a mesh for bullet softbody.

todo: create some example/demo.blend.

compound object.
This patch modifies the way the setParent actuator and KX_GameObject::setParent() function
works when parenting to a compound object: the collision shape of the object being parented
is dynamically added to the coumpound shape.
Similarly, unparenting an object from a compound object will cause the child collision shape
to be dynamically removed from the parent shape provided that is was previously added with
setParent.
Note: * This also works if the object is parented to a child of a compound object: the
collision shape is added to the compound shape of the top parent.
* The collision shape is added with the transformation (position, scale and orientation)
it had at the time of the parenting.
* The child shape is rigidly attached to the compound shape, the transformation is not
affected by any further change in position/scale/orientation of the child object.
* While the child shape is added to the compound shape, the child object is removed from
the dynamic world to avoid superposition of shapes (one for the object itself and
one for the compound child shape). This means that collision sensors on the child
object are disabled while the child object is parent to a compound object.
* There is no difference when setParent is used on a non-compound object: the child
object is automatically changed to a static ghost object to avoid bad interaction
with the parent shape; collision sensors on the child object continue to be active
while the object is parented.
* The child shape dynamically added to a compound shape modifies the inertia of the
compound object but not the mass. It participates to collision detection as any other
"static" child shape.

a game flag). audio initialization delays startup of game engine 2 seconds
add -nojoystick commandline option: it takes 5 seconds everytime to start the game engine, while there IS no joystick.
In other words: blender -noaudio -nojoystick improves workflow turnaround times for P - ESC from 7 seconds to 1 second!
Improved Bullet soft body advanced options, still work-in-progress. Make sure to create game Bullet soft bodies from scratch, it is not compatible with last weeks builds.

fake world coordinate system to game soft bodies, although the vertices are already in world space.
Added Bullet/Gimpact concave collision detection to Blender. If your build system isn't updated yet, please add extern/bullet2/src/BulletCollision/Gimpact/*
This allows moving/dynamic concave triangle meshes (decomposing meshes into compound convex shapes, and using 'compound' shapes is still preferred)
|

set a fake world transform for game soft bodies, based on center of the AABB, so visiblity and some game logic works. note: this world transform is not smooth.
|

copy normals for soft body vertices, to get proper lighting
|
|
use shape matching by default for game soft bodies
store soft body index for game vertices

Added SetDeformer/GetDeformer() to KX_GameObject.
Store mapping between graphics/soft body vertices (work-in-progress)
Real-time soft body integration is still very premature, but
for a quick preview, see this testfile:

subversion.
The Physics button controls the creation of a physics representation
of the object when starting the game. If the button is not selected,
the object is a pure graphical object with no physics representation
and all the other physics buttons are hidden.
Selecting this button gives access to the usual physics buttons.
The physics button is enabled by default to match previous Blender
behavior.
The margin parameter allows to control the collision margin from
the UI. Previously, this parameter was only accessible through
Python. By default, the collision margin is set to 0.0 on static
objects and 0.06 on dynamic objects.
To maintain compatibility with older games, the collision margin
is set to 0.06 on all objects when loading older blend file.
Note about the collision algorithms in Bullet 2.71
--------------------------------------------------
Bullet 2.71 handles the collision margin differently than Bullet 2.53
(the previous Bullet version in Blender). The collision margin is
now kept "inside" the object for box, sphere and cylinder bound
shapes. This means that two objects bound to any of these shape will
come in close contact when colliding.
The static mesh, convex hull and cone shapes still have their
collision margin "outside" the object, which leaves a space of 1
or 2 times the collision margin between objects.
The situation with Bullet 2.53 was more complicated, generally
leading to more space between objects, except for box-box collisions.
This means that running a old game under Bullet 2.71 may cause
visual problems, especially if the objects are small. You can fix
these problems by changing some visual aspect of the objects:
center, shape, size, position of children, etc.

account parent inverse node. Fix scaling bug on instantiation of compound shape: child shape didn't have correct shape. Note: global scaling doesn't work on compound shape (limitation of Bullet); don't set any scale on the top dynamic object.

the features that are needed to run the game. Compile tested with
scons, make, but not cmake, that seems to have an issue not related
to these changes. The changes include:
* GLSL support in the viewport and game engine, enable in the game
menu in textured draw mode.
* Synced and merged part of the duplicated blender and gameengine/
gameplayer drawing code.
* Further refactoring of game engine drawing code, especially mesh
storage changed a lot.
* Optimizations in game engine armatures to avoid recomputations.
* A python function to get the framerate estimate in game.
* An option take object color into account in materials.
* An option to restrict shadow casters to a lamp's layers.
* Increase from 10 to 18 texture slots for materials, lamps, word.
An extra texture slot shows up once the last slot is used.
* Memory limit for undo, not enabled by default yet because it
needs the .B.blend to be changed.
* Multiple undo for image painting.
* An offset for dupligroups, so not all objects in a group have to
be at the origin.

the object is applied. The scale is now applied to the shape before the creation of the rigid body.

slowdown.
The root cause of this bug is the fact that Bullet shapes
are shared between duplicated game objects. As the physics
object scale is stored in the shape, all duplicas must
have the same scale otherwise the physics representation
is incorrect.
This fix introduces a mechanism to duplicate shapes at
runtime so that Bullet shapes are not shared anymore.
The drawback is an increased memory consuption.
A reference count mechanism will be introduced in a
later revision to keep Bullet shape shared between
duplicas that have the same scale.

Sorry, no armatures fix yet.

including implementation. hope it works, and doesn't break to much.
it bakes physics objects transform into ipo, every frame of the running gameengine.
When you disable and run the game again, it clears the ipo's again. just for physics objects at the moment.
(perhaps some better UI in the future?)
