From 167b1b32c5ff30d514253072ce54513112c03d4d Mon Sep 17 00:00:00 2001 From: =?utf8?q?Christian=20K=C3=B6nig?= Date: Mon, 12 Dec 2011 15:27:34 +0100 Subject: [PATCH] g3dvl/compositor: improve dirty area handling MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Take viewport and scissors into account and make the dirty area a parameter instead of a member.
