SVGs not loaded via proxy, causing tainted canvas

[Paratron]

Hi,
I had the issue that html2canvas would not use the given proxy script to fetch SVG images. I don't know why it was built this way, but the code in imageloader.js would never allow an SVG to be fetched by the proxy.

This causes the canvas to be tainted - even when allowTaint was set to false. I updated the method to only load SVGs directly, when no proxy script has been defined.

I already created pull request #802 if you want to pull the fix into the project.

I ran into the same problem! I have a svg file in a new browser.

This line: https://github.com/niklasvh/html2canvas/blob/master/src/imageloader.js#L63
if (this.isSVG(src) && !this.support.svg && !this.options.allowTaint) {
is falsy because of this.support.svg. Which is fine.
However, this line:
} else if (this.isSameOrigin(src) || this.options.allowTaint === true || this.isSVG(src)) {
then is true, and loads our svg with cors set to false which per definition taints the canvas :|.

Questions:

• I assume SVGContainer is for browser that don't support SVG?
• Why load an SVG with cors false?
