From c9cb9cf0502f4ca179ed1b4dd763c94912843d38 Mon Sep 17 00:00:00 2001 From: Brian Paul Date: Fri, 18 May 2012 14:45:20 -0600 Subject: [PATCH] mesa: use F_TO_I() instead of IROUND() MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Use it where performance matters more and the exact method of float->int conversion/rounding isn't terribly important. There should no net change here since F_TO_I() is the new name of the old IROUND() function.
