I'm very curious about the idea of making this be PP_VARTYPE_BUFFER (meaning
PPB_Buffer), and then just commenting that a PPB_Buffer can be converted to a
ArrayBuffer in JS.

PPB_Buffer is a PP_Resource, whereas I really want this to be a PP_Var. It's a
shame to have the duplication; maybe video could eventually move to using
ArrayBuffer?
