fix(examples): ExOgreRGBDStream crashes on startup
Description
ExOgreRGBDStream crashes on startup with the error [fatal] [libs/viz/scene2d/SRender.cpp:199] Assertion 'false' failed: Bad scene configurationType, unknown xml node : viewport
. It seems that the XML example is wrong.
Steps to reproduce
Simply try to launch ExOgreRGBDStream. I got the crash on Ubuntu 21.10, but I wouldn't see why it would work on other platforms.
Functional specifications
There is a bug indeed in this sample, however, it is quite outdated and irrelevant today because the only RGBD camera supported in Sight are the Intel Realsense devices. However, we have a dedicated sample for it. I propose to remove ExOgreRGBDStream and add the TF editor in ExRealRense, because that was a missing useful feature.
Technical specifications
Initially, this is a regression because of the API change in the scene2D !729 (merged). We just need to adapt the code accordingly in ExOgreRGBDStream and then move the TF editor code in ExRealSense. Then we can remove ExOgreRGBDStream.
Test plan
Launch the app.
