[Mesa-dev] [PATCH 00/16 v3] i965: Enable winsys MSAA on gen >= 6

[Chad Versace]

For test results, see the commit message in patch 16. The summary is that
piglit, oglconform, and xonotic are all happy. It was nice to play xonotic
without seeing ugly, jagged edges.

Many of these patches have already been reviewed. I'm not seeking additional
review for those, although additional review is welcome.

Patches 1-4 accomplish allocating the miptrees for DRI2 buffers.

Patches 5-11 accomplish the automatic downsample and upsample operations
needed for glFlush, glReadPixels, and software fallbacks.

Patches 12-15 enable winsys MSAA by advertising MSAA configs.

v3: Incorporate review by Anholt. Kill file brw_blorp_orphans.cpp. Move
definitions of intel_miptree_up/downsample into intel_mipmap_tree.c. Check
against mt->num_samples > 1 rather than > 0. Probably a few more things
I can't recall, but I've made notes for all the changes in individual commit
messages.
