OpenGL 1.0 had texturing.  It just didn't have texture objects.  If you 
wanted more than one texture you had to use display lists.

glNewList(tex0, GL_COMPILE);
glTexImage2D(GL_TEXTURE_2D, ...);
glTexParameteri(GL_TEXTURE_2D, ...);



That's just as good as encapsulating state in an object, right? :) 
That's why OpenGL 1.1 came out so quickly after 1.0.
