It’s actually a documentation bug, not the code (hopefully).  
Recently I looked into Multisampling because my app has antialiasing when it didn’t suppose to have (aaNone, it is not because of CGE, no worries) and I found the following info

```auto
You can always read OpenGL GL_SAMPLE_BUFFERS_ARB ...
Actually, we already initialize global CastleGLUtils.GLCurrentMultiSampling ...

```

However, it doesn’t look like you have this global at all. I went through the includes, then checked on github but it’s nowhere there.

The same text landed on the documentation pages.

Thanks for reporting! We moved it to a read-only property inside the singleton `GLFeatures`, so it should be `GLFeatures.CurrentMultiSampling`.

Fixed in [Fix API docs to lead to @link(TGLFeatures.CurrentMultiSampling GLFeat… · castle-engine/castle-engine@e3cdfe5 · GitHub](https://github.com/castle-engine/castle-engine/commit/e3cdfe566d630b704b63c3321fd2b396b09814b0) , comment now says:
