No display in IE, bad display in Safari

```
OS: Windows 8.1 (PC)
Browsers used:
- Firefox 35.0.1
- Chrome 40.0.2214.115 m
- Safari 5.1.7
- Internet Explorer 11.0.9600

jsc3d doesn't work flawless in all browsers. My main issues are with Safari nd
IE. I'm using a .3ds file, maybe the problem lies herein.

- In IE, I can't get the model to show at all. The canvas shows the gradient as
specified in the viewer's parameters, but no loading bar nor model. When
including the IE script , jsc3d doesn't work in ANY
browser, and the canvas is shown blank.
There is also no difference in IE when I remove the WebGL rendering or put it
online.

- In Safari, the model is loaded but it's extremely slow/laggy and the model
looks horrible. Probably the same issue as described here:
code.google.com/p/jsc3d/issues/detail?id=8

- Everything works perfectly in Firefox. With WebGL rendering, it looks very
smooth too.
- In Chrome I couldn't get it to work, until I read on one of the other issues
here that Chrome has some special way of handling local file security. When I
uploaded the files online, it displayed fine as well.

An additional note: In all four browsers the online samples provided work just
fine. It may be the .3ds causing these issues.

Any ideas? Thanks!

Start by reproducing the .3ds case in the provided online samples across Firefox, Internet Explorer 11, and Safari. Inspect jsc3d_ie.js and jsc3d-full-1.6.5, comparing the failing case with the working samples. Done means the model and loading bar render in IE, Safari display and performance are usable, and Firefox and Chrome remain unaffected.
