I don't recall ever being used on windows -- it was never generic enough for that -- but the intent of that method is indeed "presentation of a surface", which seems what's in question here. I wish we had a proper cross-platform "present" method we could use everywhere. But yes, I'd prefer we'd try use/extend the exiting "flush_frontbuffer" before attempting to add a new method. > The void* backend thingy is a remnant from the windows days. I'm pretty sure this predates windows support in gallium and is based of DRI's flushFrontBuffer method...
