Better support for multiple canvases to be created

html2canvas can be a slow if you need to make a canvases for multiple items, because the whole document needs cloned multiple times, it would be nice to have a way to send multiple items to be converted to canvas.

Few different ways would suffice

• Pass a collection of node to create canvases for, then the promise would return an array

var nodes = [];
// fill nodes
html2canvas(nodes).then(function(canvases){
// use canvases
});

• Piggy back the removeContainer option and allow you to reference an iframe to operate on in the options. This gives a greater amount of flexibility to the end user

var nodes = [];
// fill nodes
var iframe;
html2canvas(node[0], {removeContainer: false}).then(function(canvas, iframe){
// use canvas
iframe = $(iframe).attr('id');
});
html2canvas(node[1], {removeContainer: true, iframe: iframe})then(function(canvas){
// use canvas
});

💡 Without touching the library, a workaround could be to make a Texture Atlas, call html2canvas over a div, get the resulting canvas and crop it accordingly to produce multiple canvases.

The bounty for this is still open for the taking…

$50 might not be enough 😆
