    glx: Fix glXQueryContext for GLX_FBCONFIG_ID and GLX_RENDER_TYPE (v2) · 5d667df6

    Just never filled in, oops. Seems to have gone unnoticed because
    normally glXQueryContext simply returns the values filled in by the
    client library when the context was created. The only path by which you
    normally get to a GLXQueryContext request is glXImportContext, and then
    only if the context is already indirect.
    However, that's a statement about Mesa's libGL (and anything else that
    inherited that bit of the SGI SI more or less intact). Nothing prevents
    a mischeivous client from issuing that request of a direct context, and
    if they did we'd be in trouble because we never bothered to preserve the
    associated fbconfig in the context state, so we'd crash looking up
    GLX_VISUAL_ID_EXT. So let's fix that too.
