Subject: Fix incorrect scale in pipeline_barrier tests
X-Git-Tag: upstream/0.1.0~9^2~74
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=d9623aad4aeb50ece827b3cdd90223cafb160cd7;p=platform%2Fupstream%2FVK-GL-CTS.git

Fix incorrect scale in pipeline_barrier tests

The ImageBlitFromImage verfication code incorrectly scales the refrence image it creates.
The test should add 0.5 to the x and y coords before scaling them.

Affects:
dEQP-VK.memory.pipeline_barrier.*

Components: Vulkan

VK-GL-CTS issue: 577
