[Bug 28798] Make BufferSource more convenient to use

--- Comment #23 from Boris Zbarsky <bzbarsky@mit.edu> ---
I think it's actually quite annoying to spec and even worse to implement for
nontrivial cases like dictionaries that contain sequences of things that might
be ArrayBuffers...

Maybe we should think carefully about where large buffers would actually be
used, other than WebGL.  If most of the rest are fully under the control of the
browser (so that once the first copy has been made the data can get handed off
without further copies), then the right solution might be to spec/implement the
simple thing, have WebGL use [UnsafeReference] and manual data extraction
(which is what it does in UAs right now anyway, right?) and leave it at that.
