Maximum texture size supported by WoW 3.3.5a?

[FiftyTifty 2]

Anyone know what the biggest texture size is for 3.3.5a? I know it has shaders for SM 3.0, so it has a mimimum of 8192x8192, but I'd like to make as few texture atlases as possible, so if it does support a max of 16384x16384, that would be great to know.
