Compatibility with Ogre 13

[simonschmeisser]

This fixes compatibility with Ogre 13.6.4, the most recent release. It requires two special cmake flags when building Ogre:

-DOGRE_NODELESS_POSITIONING:BOOL=TRUE \
-DOGRE_GLSUPPORT_USE_EGL:BOOL=FALSE \

Sorry for the delay reviewing this. Your changes look good.
It would be great to include Ogre 1.13 in the GHA tests here:

rviz/.github/workflows/ci.yaml

Line 17 in 93ac44b

ogre: ["1.9", "1.12"]

To this end, we would need to setup a .deb repository to install libogre-13.x-dev from, which is done here:

rviz/.github/workflows/ci.yaml

Line 27 in 93ac44b

AFTER_INSTALL_TARGET_DEPENDENCIES: apt install -qq -y libogre-${{ matrix.ogre }}-dev

However, your PPA doesn't provide a -dev package and it is targeted at Jammy only.
Could you please augment?

[simonschmeisser]

I'll check what it takes to build it on Focal, sure.

What do you mean by "doesn't provide a -dev package"? https://launchpad.net/~s-schmeisser/+archive/ubuntu/ogre-13/+packages has libogre-13.6-dev

Note that I failed in getting gazebo to work with Ogre 13 as they use insane amounts of private API which is no longer accessible (or partially removed) in Ogre 13.

You are right. I just have seen the top-level entries.

I just want to ensure that future changes won't break Ogre 13 compatibility again...
