Re: [Public WebGL] Requirements for bufferData don't make sense given the IDL

In particular, it says:

      If the passed data is null then an INVALID_VALUE error is generated.

    But the IDL declarations for this method don't allow |data| to be
    null; an attempt to pass null will throw during the WebIDL overload
    resolution algorithm.  Was this requirement meant to be on
    bufferSubData (which does allow null to be passed)?  Or is
    bufferData supposed to have an overload that allows null?

Until recently, there were no nullable declarations in the spec at all. Some were added recently, and this is still being ironed out; this may be part of that. See https://www.khronos.org/webgl/public-mailing-list/archives/1203/msg00084.html. (https://www.khronos.org/webgl/public-mailing-list/archives/1203/msg00086.html is also relevant; it's an attempt to remove the need for some functions to be nullable.)

That's great as history goes; it doesn't resolve the issue.
