If you can find a Wayland compositor that is written to composite with
GLES1, that's all you need from the "Wayland side". (Yeah, this has
nothing to do with Wayland per se.) Compositing in itself without any
effects is very simple, as long as you get the textures up.

Or, if you find a Wayland compositor written to use desktop OpenGL for
compositing and does not use features your GL driver does not expose,
that's good too.

Absolutely nothing about Wayland limits your choice of the GL flavour -
even more so as the compositor is not running *on* Wayland.

Also, the question of running GL apps on Wayland is a whole another
matter. There used to be a common misconception that Wayland had
something to do with only allowing GLES.

Finally, there is the option of software rendering for composition...
