//  DevalVR + QuickTime + PTviewer + Flash + Spi-v  Javascript workaround
//	Author: fiero http://www.devalvr.com
//  Version: 1.3.5  adapted by erik leeman
//  ----------------------------
//  modifications by erik leeman
//  a. changed qt 'controller' from 'true' to 'false'
//  b. changed 'function insertpanoramadata': added extra parameter
//  ----------------------------
//	To embed a panorama just include these lines in your HTML file (change filenames):
//
//	<SCRIPT type="text/javascript" src="detectvr.js"></SCRIPT>
//	<SCRIPT type="text/javascript">
//		writecode("fileForQT.mov","fileForDevalVR.mov","fileForJava.jpg","fileForFlash.swf","fileForSPIV.jpg","100%","94%");
//	</SCRIPT>
//  
//
//	NOTE: To use Spi-v viewer, place "SPi-V.dcr" file in same folder that HTML file, 
//        you can find it here: http://www.fieldofview.com
//
//  	See this page for help: 
//		http://www.devalvr.com/paginas/soporte/htmlconfig.html#javascript
//	
// 	IMPORTANT: Use this file at your own risk
