From 9b6041bf62cfd2b0be62134ff6ee0fd488ce5921 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Samuel=20R=C3=B8dal?= Date: Wed, 12 May 2010 12:37:47 +0200 Subject: Modified QPainter and QPixmap benchmarks to use raster pixmaps. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit These benchmarks are not written in a way that supports robust benchmarking of asynchronous pixmap backends.
