I'll look into this now

from abacus.

ArrayBufferViews ( ie. Float32Array objects ) aren't built from Array.prototype

> var f = new Float32Array([ 1, 2 ])

> Array.isArray(f);
false

> f.slice
undefined

I'll see what I can find about copying ArrayBufferViews

from abacus.

Copies can be made by constructing a new typed array with the original as its first argument.

But I am not sure yet how to test whether a given object is an ArrayBufferView in a clean way. Nor how to generalize such construction.

I'm not opposed to having a check for instanceof ArrayBufferView and then creating a copy base on that, but is there anyway to tell which type to make? (ie. Float32, Float64 etc. )
