Ok, I did #2 but I think to avoid confusion I don't want to send it to the
list just yet, since it depends on the minor fixups that I've made to my
patch series based on Eric's comments--if I just sent the patches to the
list, they would appear to apply cleanly, but they wouldn't work properly.
If you want to have a look at it, pull from git://
github.com/stereotype441/mesa.git and look at the top two commits on the
vue_map branch.
