From 57876fee3872f4f224feeeb56eea6d2e10858fe9 Mon Sep 17 00:00:00 2001 From: Jordan Justen Date: Wed, 21 May 2014 22:34:26 +0000 Subject: [PATCH] meta blit: Set Z texcoord during meta blit to sample the correct layer If the source renderbuffer has a depth > 0, then send a Z texcoord which is set to the source attachment Z offset. This fixes piglit's gl-3.2-layered-rendering-gl-layer-render with the GL_TEXTURE_2D_MULTISAMPLE_ARRAY case test on i965/gen8.
