    GLX/DRI2: handle swap event swap count wrapping
    Create a new GLX drawable struct to track client related info, and add a
    wrap counter to it drawable and track it as we receive events.  This
    allows us to support the full 64 bits of the event structure we pass to
    the client even though the server only gives us a 32 bit count.

I'm not 100% sure about this commit since the issue is not always reproducible, but it seems likely this can be it.

This is with r300g driver, RV530 card. Assigning to mesa core because of the bisect results, I did try the llvmpipe, to see if other drivers are also affected, however it is so slow here I can't change any settings.
