From 9b5f5de9e9efd6a0c0f53806c0f4b5890c84f98b Mon Sep 17 00:00:00 2001 From: Masanori Kakura Date: Wed, 28 Dec 2016 22:21:02 +0900 Subject: [PATCH] st/nine: Don't call u_box_union_* when dirty region is empty When dirty region is empty, u_box_union_* incorrectly expands the new region. This fixes broken font rendering issue in WOLF RPG Editor v2.10 games.
