I started writing this patch but I've hit a stumbling block while trying to make use of it in Mesa. Adding the new request requires altering the version of the wl_compositor and wl_surface interfaces. The problem is that Mesa can't really use the new request unless the wl_surface object is using the new version. However, the version of the interface that is actually in use is determined by the application when it binds the compositor object. As far as I can tell, there is no way for Mesa to determine what version the surface proxy object is using. Potentially we could add some API to query this, but I think even that wouldn't be ideal because really Mesa wants to know the interface version number right up front when the display is initialised so that it can determine the value to report for EGL_MIN_SWAP_INTERVAL. I'm not sure how to proceed with this. It seems like ideally Mesa should be able to make requests on the surface using its own binding of the compositor object so that it's not tied to the version of the interface that the application is using. I guess that would imply that it would have some way to get its own resource for the surface. That seems like quite a packed can of worms though. Anyone have any ideas? I'll attach the work in progress patches anyway just for good measure.
