From c00282102aea387e8c0fb29811d0ea8f010f145a Mon Sep 17 00:00:00 2001 From: Ian Romanick Date: Wed, 24 Feb 2010 16:05:20 -0800 Subject: [PATCH] swrast: Remove _swrast_write_index_span and associated code After all the recent color-index rendering removal, _swrast_write_index_span is no longer used anywhere.
