## rviz

```
* Forward ported #707
  Update frame_manager.cpp
  Changed TF listener to use a dedicated thread.
* Fix segfault on exit for OSX
* Fixed rendering of mesh resource type markers with respect to texture rendering and color tinting
* Fix memory leak in BillboardLine destructor (material not being destroyed correctly)
* EffortDisplay: Added a check to avoid segfaults when receiving a joint state without efforts
* Speed up point cloud rendering
  this is mostly caching some computations and using proper loop iterations
