From 88a630121dbcb65ff7a87ebdeb5d916e977a64f0 Mon Sep 17 00:00:00 2001 From: Kenneth Graunke Date: Thu, 19 May 2016 21:13:29 -0700 Subject: i965: Implement a BLORP path for CopyImage and prefer it over Meta. We're dropping Meta in favor of BLORP everywhere we can. This also fixes bugs when copying cubemaps to 2D, which is currently broken in the meta pass. BLORP just works.
