WGL semantics are similar to GLX -- just different names --, so I don't expect any problem adapting st/wgl to st_api.h. Leaving it broken is not an option though, since it is a very important component for us. If you could do the initial rough conversion of st/wgl to st_api.h I'd gladly test it and polish it. I've looked at http://cgit.freedesktop.org/~olv/st_api/tree/st_api.h , and all looks very sensible. The only thing I don't understand, perhaps due to my EGL ignorance, is st_context::lock/unlock_resource(). What do they exactly accomplish? Is there some EGL visible APIs that map exactly to this? > As Jakob drafted the first version of the interface, I believe he also wanted > to remove "screen->flush_front" and "screen->update_buffer".

I think st_api's st_framebuffer::flush_front accomplishes this nicely. BTW, I'd prefer the name "present" instead of "flush_front". It's a more common and intuitive name for this operation.
