 * GL_EXT_texture_storage == GL_ARB_texture_storage
 * If subsuming, the DSA related part, i.e. 'glTextureStorage[123]DEXT' collides w/ OpenGL 4.5,
 * which supports non DSA ''glTextureStorage[123]D' variants.
 * Hence the DSA related part is not renamed!
 * To avoid duplication, we add GL_EXT_texture_storage here as well.
 * Extension is completed via https://cvs.khronos.org/svn/repos/ogl/trunk/doc/registry/public/api/gl.xml
 * See: gl-common-extensions.cfg
