- Fixed an error in Matrix::createOrthographicOffCenter.
- Changed orthographic camera mode to have an origin of bottom left, with +Y up and +X to the right.
- Added configurable character spacing to the Font class.
- Changed Scene:addNode and Node:addChild to add nodes to the back of the list instead of the front, so that traversal order matches the order in which nodes are added.

Added support for specifying front facing polygon mode (CW or CCW) in RenderState.
Fixed issue with parsing tags in .scene file for nested nodes.
Added ETC1 compressed texture support.
Added support for dynamic meshes rigid bodies via btConvexHull, which is a more efficient approximation of a convex mesh. More accurate higher resolution static triangle meshes are still supported via btBvhTriangleMeshShape when a mass of zero is specified.

Updated the physics sample in the sample browser to use a dynamic mesh rigid body for the duck model.
