Perhaps we should instead call the param "convertTo" or something like that and have a unique set of enums (including NO_CONVERSION) to better distinguish the operation from simply describing the internalformat, as is done in the raw form of texImage2D.

But these function already diverge. They are a bridge between HTML and WebGL. They also support y flipping and alpha premultiplying, which are divergent. We need to make them useful to the HTML author, not matching OpenGL.
