How much work (e.g. work days per single engineer) would it be to get
the "Multiplane Group"-functionality ported over to the Xorg fb driver ?
After doing a quick look over it's functionality it's something which
could be a great benefit for many applications (including Mozilla and
the Qt toolkit) if most of the Xorg drivers would support it...
