Subject: layers: Refactor CmdFillBuffer
X-Git-Tag: upstream/1.1.92~1582
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=99a86825c8b22db7d9727678befffe8ab94a251c;p=platform%2Fupstream%2FVulkan-Tools.git

layers: Refactor CmdFillBuffer

Separated validation from state updates, refactored for pre/post
and moved these functions out of core_validation. Also updated for
coding style.
