Should set .elm property on created vnodes

[stucox]

I wonder if virtualize() should set the .elm property on the nodes it creates, such that:

var div = document.createElement('div');
var vnode = virtualize(div);
console.log(vnode.elm == div)  // true

Reasoning:

My use case for snabbdom-virtualize is to “pick up where I left off” with a server-rendered DOM: snabbdom’s patch(oldVnode, newVnode) function expects both oldVnode and newVnode to be virtual, so I was hoping to virtualize the existing DOM before patch()ing with the next state.

However, snabbdom needs the .elm reference to tie elements up properly, which snabbdom-virtualize doesn’t set.

Is there any reason why setting .elm to refer to the source node would be a bad idea?

Alternatively if hooks.create() callback passed the source node, users of this lib would be able to add this functionality themselves.

This should be resolved in 0.6.0 thanks to @katyo's #14
