Instead of https://gitlab.winehq.org/wine/wine/-/merge_requests/8496, leaving context sharing for later.
-- v4: win32u: Remove now unnecessary opengl_drawable hdc member. winewayland: Use a distinct wayland_pbuffer struct for pbuffers. win32u: Implement generic EGL driver pbuffer surface. win32u: Avoid releasing opengl drawable within drawables_lock. win32u: Avoid calling detach, flush or swap on pbuffer drawables. winemac: Remove now unnecessary pbuffer tracking.

Hmm... I see, quite unfortunate that wayland GL has neither PBuffer nor Pixmaps... *sigh*.
FWIW, I have filed https://gitlab.freedesktop.org/mesa/mesa/-/issues/13454. It seems the time may be ripe to add Wayland EGL pbuffer support (although I am not sure how soon I will be able to get to it myself), so hopefully we will be able to remove this point of friction going forward. Let's see what upstream thinks.

v3: Keep winewayland pbuffer backed by wl_surface, split them from window drawables so they don't get in the way of later refactoring. @afrantzis all they need is a wl_surface and an wl_egl_window right? Could you confirm whether https://gitlab.winehq.org/wine/wine/-/merge_requests/8498/diffs?commit_id=50... would work?
Yes this should be enough. Note that we still need a way to expose "fake" pbuffer capable formats.

Thanks! I'm working on getting a generic swapchain implementation based on FBOs and exportable images anyway, so eventually we might be able to use it to implement pbuffers without requiring platform support.
Here I mostly just wanted to get pbuffers out of the way so I could make more changes the OpenGL window surface interface and make it converge with Vulkan surfaces, and I was mildly annoyed to find another lacking mechanism I assumed Wayland had already ;), but no big deal it should be fine like this.
