    meta/generate_mipmap: Work-around GLES 1.x problem with GL_DRAW_FRAMEBUFFER

    GL_DRAW_FRAMEBUFFER does not exist in OpenGL ES 1.x, and since
    _mesa_meta_begin hasn't been called yet, we have to work-around API
    difficulties.  The whole reason that GL_DRAW_FRAMEBUFFER is used instead
    of GL_FRAMEBUFFER is that the read framebuffer may be different.  This
    is moot in OpenGL ES 1.x.

    I have another patch series that would also fix this (by removing the
    calls to _mesa_BindFramebuffer and friends), but it's not quite ready
    yet... and I think it may be a bit heavy for some stable branches.
    Consider this a stop-gap fix.
