## rviz

```
* Fix an issue with rendering laser scans: #762 <https://github.com/ros-visualization/rviz/issues/762>
* Fix an issue with using boost::signal instead of boost::signal2 with tf
  tf recently moved to boost::signal2, so the effort display needed to be updated too
  I made it so that it would conditionally use boost::signal2 if the tf version is greater than or equal to 1.11.3
  I also fixed some compiler warnings in this code
  closes #700 <https://github.com/ros-visualization/rviz/issues/700>
