New Nodes

• actor/GetChildrenPhysicsRBDProperties
• actor/GetChildrenProperties
• actor/GetPhysicsRBDProperty
• actor/SetGeometryInstanceAttribute
• actor/SetGeometryInstancePositions
• actor/SetGeometryInstanceQuaternions
• actor/SetGeometryInstanceScales
• actor/SetGeometryInstanceTransforms
• actor/PhysicsPlayerUpdate
• actor/PhysicsRBDResetAll
• actor/SetPhysicsRBDAngularVelocity
• actor/SetPhysicsRBDLinearVelocity
• sop/PhysicsPlayer

General Improvements

• cop/video: allow import from multiple urls or from an existing html element
• sop/particlesSystemGPU: refactor to allow cloning. It was previously not possible to plug the particles node into a merge node. This therefore makes it easier to add the particles to other scene elements.
• actor nodes like actor/setObjectAttribute have now 2 outputs, 1 for the trigger and 1 for the current object, so that they can be chained. This can be useful when not using the current object.

Physics Improvements

• cuboid, cone and cylinder collider have a border radius
• add heightfield collider
• add sop/physicsPlayer
• add sop/PhysicsWorld debug view

Bug fixes

• ensure an errored CSG node correctly propagates error to parent node to prevent staling downstream nodes

Breaking Changes

• the instance attribute instanceOrientation, used by the sop/instance, has been renamed to instanceQuaternion. This should only impact scenes using it directly in shaders via a gl/attribute node.
