Specifically what this means is that there isn’t OpenGL support in it (we need OS/platform-level support for OpenGL for creating and switching (making current) OpenGL contexts), which likely needs to be done with WebGL, which most probably needs to be done in the .js file in the broadway subdir in gdk/. GTK+-4.x is going to switch to GL drawing, at least for the majority of the various components, which makes OpenGL support a requirement.
AFAIK, the backends that have the needed support are x11, Wayland, mir and Windows.
I think there are two main possibilities:
1) Remote the OpenGL commands over the network to JS running in the Broadway renderer's HTML page, assuming that quasi-OpenGL ES 2 is enough to do GTK+'s rendering (or that any necessary bits can be emulated in WebGL).
I'm not sure how easy either is, though both should be possible.
