// bh 5/2009  -- Support for XHTML using jmolSetXHTML(id)

// bh 1/2010  -- adds option to run a JavaScript function from any Jmol control. 
//               This is accomplished by passing an array rather than a script:
//               jmolHref([myfunc,"my param 1", "my param 2"], "testing")
//               function myfunc(jmolControlObject, [myfunc,"my param 1", "my param 2"], target){...}
//               and allows much more flexibility with responding to controls
// bh 4/2010  -- added jmolSetMemoryMb(nMb)
// ah 1/2011  -- wider detection of browsers; more browsers now use the object tag instead of the applet tag; 
//               fix of object tag (removed classid) accounts for change of behavior in Chrome
// bh 3/2011  -- added jmolLoadAjax_STOLAF_NIH
// ah 9/2011  -- Applet is now wrapped in a <span> tag (might break existing user code).
//               Added jmolSwitchToSignedApplet(); replaces an applet with the signed applet, 
//               preserving size, model and state; an additional script may be specified. 
//               Note: as a result, unsigned and signed applets may coexist in a page.

// Note added 12:41 PM 9/21/2008 by Bob Hanson, hansonr@stolaf.edu:

// JMOLJAR=xxxxx.jar on the URL for this page will override
// the JAR file specified in the jmolInitialize() call.

// The idea is that it can be very useful to test a web page with different JAR files
// Or for an expert user to substitute a signed applet for an unsigned one
// so as to use a broader range of models or to create JPEG files, for example.

// If the JAR file is not in the current directory (has any sort of "/" in its name)
// then the user is presented with a warning and asked whether it is OK to change Jar files.
// The default action, if the user just presses "OK" is to NOT allow the change. 
// The user must type the word "yes" in the prompt box for the change to be approved.

// For a simple change to the signed applet in the same original directory (if it's available),
// you can use JMOLJAR=SIGNED on the URL.

// If you don't want people to be able to switch in their own JAR file on your page,
// simply set this next line to read "var allowJMOLJAR = false".
