From 83d9cd4e96824a7533e19b596efd6f159254557f Mon Sep 17 00:00:00 2001 From: Ulrich Sibiller Date: Wed, 30 Oct 2019 18:26:31 +0100 Subject: damage: Don't rewrite Text ops to GlyphBlt ops This backport of a 2013 Xorg fix changes miext/damage.c so that the text functions (damageText, damage{Poly,Image}Text{8,16}) finally are very similar to the changes that NX introduced in 2007 with nxagent-3.0.0-28. Fun fact: the original freedesktop bug mentioned below is from 2005 and the fix came in 2013... Next commit will be the complete drop of NXdamage.c. commit 0f3f8e4295d4c05f33b93e0ffd2f6f8cd5759bf7 Author: Adam Jackson Date: Wed Aug 21 11:13:11 2013 -0400 damage: Don't rewrite Text ops to GlyphBlt ops There's no particularly good reason to, and it breaks Xnest.
