From d8b34ab0604d80d0be22b8b78e9aa6bf4fac7db0 Mon Sep 17 00:00:00 2001 From: Sian Cao <yinshuiboy@gmail.com> Date: Thu, 27 Oct 2016 15:19:32 +0800 Subject: texture: Support copy_sub_image The patch is used to implement feature similar with kwin blur effect by being abel to copy partial of framebuffer contents as texture and do post blurring.
