From 20fedfd80aa2402d2033215c538894c9f81e422a Mon Sep 17 00:00:00 2001 From: Brian Paul Date: Fri, 31 Jan 2014 17:38:35 -0700 Subject: mesa: don't signal _NEW_TEXTURE in TexSubImage() functions MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit glTexSubImage(), glCopyTexSubImage() and glCompressedTexSubImage() only change the texel data, not other state like texture size or format. If a driver really needs do something special it can hook into the corresponding driver functions or Map/UnmapTextureImage(). This should avoid some needless state validation effort.
