OBJ impoter does not work in IE - see fix

[AdamMcM]

Description of the problem

Loading OBJ files in IE (in my case IE 11) causes a state exception in the Ajax request object. This occurs when, the xhr is set to "arraybuffer". This is a known problem in IE. The work around is to not set xhr to "arraybuffer", but keep its default as "text". Download the file as a string, and then convert it to an arraybuffer before passing it to ok()

Here is the full load() function with comments at the changes.

   function load(url, ok, error) {
            var xhr = new XMLHttpRequest();
            //xhr.responseType = "arraybuffer";  // *** CHNAGED

// xhr.addEventListener('progress',
// function (event) {
// // TODO: Update the task? { type:'progress', loaded:event.loaded, total:event.total }
// }, false);
xhr.addEventListener('load',
function(event) {
if (event.target.response) {
var s = event.target.response; // *** CHANGEs HERE!!!
var uintArray = new Uint8Array(s.split('').map(function(char) {return char.charCodeAt(0);}));
ok(uintArray);
} else {
error('Invalid file [' + url + ']');
}
}, false);
xhr.addEventListener('error',
function() {
error('Couldn't load URL [' + url + ']');
}, false);
xhr.open('GET', url, true);
xhr.send(null);
}
})();
