Supposedly the rest contains the window name.
Would make sense to export that as metadata IMO.

I guess you could just pick out the right bytes directly, like
red = buf[4];
red = buf[6];
red = buf[8];
buf += 10;
I am also completely unclear on whether the "flags" should be
respected, in which case it should be something along the lines of
red = buf[9] & 1 ? buf[4] : 0;
etc.
