Fortunately backend_dispatch already allowed to omit these on specific backends (https://github.com/MarijnS95/softbuffer/compare/android-surfacecontrol), but it's good to make them disappear from the public API too in light of having a separate buffer creation API.

it's good to make them disappear from the public API too in light of having a separate buffer creation API.

If we did want to do it, then this PR would perhaps be the wrong approach, since a Buffer would still contain a wl_buffer, which would mean it relied on the connection to the Wayland display server still being alive IIUC.

That said, I'm not really convinced yet myself that would be such a good idea, there's a lot of complexity in allowing manual memory management of buffers.

Anyhow, I'm gonna merge this in a few days unless you have any objections?
