[Nouveau] [RFC PATCH] nv50: adjust blit_3d logic

[Ilia Mirkin]

---

So... this fixes a whole bunch of EXT_framebuffer_multisample tests, and the
ones that still fail appear to do so due to some resolve error, rather than
some "this is the wrong image" type errors. Perhaps it needs a 2d-style "move
coordinates over a sub-texel" logic. But I'm unclear what these vertices are,
I arrived at this through trial-and-error.
