Detailed Description
This is implemented as a separate element from the TextureImageElement so the texture image can be changed without blowing caches containing shapes-- shapes need to know if texturing is going on or not so they can decide to send down texture coordinates or not.
This is set by the GLTextureImageElement and the GLTextureImageElement; the interaction between the three is a little complicated. Each of the other two elements always sets up the GL texture state appropriately; however, texturing is only enabled if both elements agree that it should be enabled (they check each other's value before calling set).
This element cannot be overridden, but, since the elements that set it check each other's value, overriding those elements has the same effect.
