From: Jarkko Pöyry Date: Tue, 21 Apr 2015 01:50:49 +0000 (-0700) Subject: Avoid accessing pixel depth directly in tcuTexCompareVerifier. X-Git-Tag: upstream/0.1.0~1738 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=d26a314f203a4923b7e8fe00c2ecb59efc6fcb97;p=platform%2Fupstream%2FVK-GL-CTS.git Avoid accessing pixel depth directly in tcuTexCompareVerifier. - Avoid accessing depth directly to make structure idential to tcuTexLookupVerifier and to make refactoring easier. - Add sanity checks to isGatherOffsetsCompareResultValid().
