I care *significantly* less about the build against 1.12, run against
1.13 case than I do about getting back to the point where I don't have
to carry around these patches to build mesa (otherwise it is just a
matter of time before I accidentally push them just because I needed
them to test whatever it was that I was intending to push ;-)

If someone wants to build on top of this and make something more
fancy, by all means.  But I really would like to push something that
removes the 1.13 dependency like today(ish), whether that be this
patchset or reverting the patches that added the 1.13 dependency and
trying again later.
