One initial comment. Likely this PR will remain unmerged for a while until there are prototype implementations of this new API. In the meantime, progress can be made on the API's semantics, addressing the TBD mentioned here, etc.

This validation related to PIXEL_PACK_BUFFER looks reversed; if a buffer's bound to that target then the textures' contents come from it. I think that instead this should say "If a WebGLBuffer is bound...", since the goal is for the texture's contents to come from the rendered element.
