Re: [Public WebGL] Should the non-typed-array overloads of uniform*v and vertextAttrib*v be IDL arrays or IDL sequences?

Early drafts of the WebGL spec used sequences for these arguments.
When arrays were added to Web IDL, they were changed to arrays, to
potentially support more efficient calls from _javascript_ to C++.
However, these entry points never mutate the incoming array.

This seems like a premature optimization; the call overhead of WebGL calls seems very unlikely to ever be a bottleneck.  (This isn't OpenGL 1.0, with function calls per vertex.)  ArrayBuffer deals with the cases where avoiding copies matters, but worrying about making a copy of four floats just seems like a distraction.
