[Mesa-dev] [PATCH 04/14] mesa: remove redundant _NEW_BUFFERS setting in ReadPixels

[Eric Anholt]

s/ReadPixels/ReadBuffer/ in the subject.

I need a bit more time to think about the NewDriverState idea in the
surrounding patches.  I don't see there being a meaningful distinction
between which state ends up in NewState versus NewDriverState in this
patch series, and I'd like to actually understand what the point is.
Unless the point is just "we're running out of bits", in which case 64
bits seems like a better solution.

I approve of more granular state updates, though.  Is this part of a
long-term plan to replace _NEW_* with more or less per-state-value
bitmasks (not just single bits) that would get set in NewDriverState?
