Subject: layers: Get rid of old CBSTATUS-based dynamic viewport and scissor
X-Git-Tag: accepted/tizen/3.0.m2/mobile/20170105.023708~174
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=9c4006684a13db43f0dbc8d0015a9ef34872ca09;p=platform%2Fupstream%2FVulkan-LoaderAndValidationLayers.git

layers: Get rid of old CBSTATUS-based dynamic viewport and scissor

These were superceded by the precise tracking of dynamic scissors and
viewports.

Fix up the tests to look for the precise errors, and get rid of the
broken clearing of static scissors & viewports, which triggered other
errors.
