From 53a5f11f0d89a044546e2bf4396f1972c9d31c4f Mon Sep 17 00:00:00 2001 From: Chris Forbes Date: Mon, 13 May 2013 21:54:36 +1200 Subject: [PATCH] mesa: Stop clamping stencil reference value at specification time All drivers now clamp this to the appropriate range for the bound stencil buffer when emitting stencil state. NOTE: This is a candidate for stable branches.
