No display in IE, bad display in Safari

[GoogleCodeExporter]

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 <script type="text/javascript" 
src="jsc3d-full-1.6.5/jsc3d_ie.js"></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!
