[Mesa-dev] [PATCH v14 29/36] i965: Add new resolve hints full and partial

[Varad Gautam]

From: Ben Widawsky <ben at bwidawsk.net>

Upper layers of the code will have the need to specify full or partial
resolves (more on this in the next patch). This code simply adds the new
enums and plumbs it in as minimally as necessary.
