3D Physics:
-Fixed "Bounce" parameter in 3D
-Fixed bug affecting Area (sometims it would not detect properly)
-Vehicle Body has seen heavy work
-Added Query API for doing space queries in 3D. Needs some docs though.
-Added JOINTS! Adapted Bullet Joints: and created easy gizmos for setting them up:
-PinJoint
-HingeJoint (with motor)
-SliderJoint
-ConeTwistJoint
-Generic6DOFJoint
-Added OBJECT PICKING! based on the new query API. Any physics object now (Area or Body) has the following signals and virtual functions:
-input_event (mouse or multitouch input over the body)
-mouse_enter (mouse entered the body area)
-mouse_exit (mouse exited body area)
For Area it needs to be activated manually, as it isn't by default (ray goes thru).
Other:
-Begun working on Windows 8 (RT) port. Compiles but does not work yet.
-Added TheoraPlayer library for improved to-texture and portable video support.
-Fixed a few bugs in the renderer, collada importer, collada exporter, etc.
