From 8a9692c29f0d5706c1ffd41886fd94f5d20d28b0 Mon Sep 17 00:00:00 2001
From: Christoph Oelckers <coelckers@zdoom.fake>

Subject: [PATCH] - fixed: The code which decided whether to clamp two sided
 middle textures used the texture size instead of the render size for the
 specific linedef, meaning that any per-sidedef scaling was ignored.
