* Here is the tricky part : getting the data.

* cf https://developer.mozilla.org/En/XMLHttpRequest/Using_XMLHttpRequest#Receiving_binary_data_in_older_browsers
* In IE <= 9, we must use (the IE only) attribute responseBody
* (for binary data, its content is different from responseText).
* In IE 10, the 'charset=x-user-defined' trick doesn't work, only the
* responseType will work :
* http://msdn.microsoft.com/en-us/library/ie/hh673569%28v=vs.85%29.aspx#Binary_Object_upload_and_download

* I'd like to use jQuery to avoid this XHR madness, but it doesn't support
* the responseType attribute : http://bugs.jquery.com/ticket/11461
