## rviz

```
* fix fragment reference in point_cloud_box.material
  Closes #759 <https://github.com/ros-visualization/rviz/issues/759>
* upgrade ogre model meshs with the OgreMeshUpgrader from ogre 1.9
* Changed TF listener to use a dedicated thread.
* Speed up point cloud rendering by caching some computations and using proper loop iterations
* Fixed rendering of mesh resource type markers with respect to texture rendering and color tinting
* Fix segfault on exit for OSX
* Fix memory leak in BillboardLine destructor (material not being destroyed correctly)
* Fix disabling of groups (#709 <https://github.com/ros-visualization/rviz/issues/709>)
  This was broken with commit 5897285, which reverted the changes in
  commit c6dacb1, but rather than only removing the change concerning
  the read-only attribute, commented out the entire check, including
  the ``parent_->getDisableChildren()`` call (which existed prior to
  commit 5897285).
* Add missing libraries to rviz link step, fixes OS X build.
* fix failing sip bindings when path contains spaces
* EffortDisplay: Added a check to avoid segfaults when receiving a joint state without efforts
* Contributors: Dirk Thomas, Hans Gaiser, Jordan Brindza, Mike Purvis, Mirko, Siegfried-A. Gevatter Pujals, Timm Linder, Vincent Rabaud, William Woodall
