From a1b1f8ff866f8ce48cfc83c9d9dd9f636d05d2a7 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Mathias=20Fr=C3=B6hlich?= Date: Wed, 29 Feb 2012 18:19:34 +0100 Subject: [PATCH] mesa: Avoid using the shine table for _tnl_RasterPos Use direct computation of pow for computing the shininess in _tnl_RasterPos. Since the _tnl_RasterPos function is still used by plenty drivers that do only need the shine table for _tnl_RasterPos but do not make use of swtnl computations, this enables pushing down the shine table computation and validation into the tnl module, which will happen in a followup change.
