Style's textColor, anchor, textSize incorrectly documented and not obfuscated correctly in compiled js

[GoogleCodeExporter]

Just a few small nits a I noticed when using this library.

Version: 3

Browser / Operating System: Any

Documentation lists 'anchor', 'textColor' and 'textSize':

 *     'styles': (object) An object that has style properties:
 *       'url': (string) The image url.
 *       'height': (number) The image height.
 *       'width': (number) The image width.
 *       'anchor': (Array) The anchor position of the label text.
 *       'textColor': (string) The text color.
 *       'textSize': (number) The text size.

But the code uses opt_textColor, opt_anchor, opt_textSize:

ClusterIcon.prototype.useStyle = function() {
  var index = Math.max(0, this.sums_.index - 1);
  index = Math.min(this.styles_.length - 1, index);
  var style = this.styles_[index];
  this.url_ = style.url;
  this.height_ = style.height;
  this.width_ = style.width;
  this.textColor_ = style.opt_textColor;
  this.anchor = style.opt_anchor;
  this.textSize_ = style.opt_textSize;
};

Further, look at http://google-maps-utility-library-
v3.googlecode.com/svn/trunk/markerclusterer/src/markerclusterer_compiled.js

You can find the compiled version of ClusterIcon.prototype.useStyle by 
inspection:

a.G=b.url;a.g=b.height;a.n=b.width;a.D=b.Y;a.anchor=b.X;a.F=b.Z;

Notice that opt_textColor is referred to as 'Y', opt_anchor as 'X' and 
opt_textSize as 'Z'.  That means to pass in an array of styles in the 
constructor while using the compiled js, you have to use X, Y, and Z as 
property names instead of their real names, which is not robust in the face 
of changes to the obfuscator.

It looks like this has been fixed now, thanks!  Feel free to close the bug.

I found a similar bug. textColor and textSize doesn't work in the compiled 
version of markerclusterer, but it does in the uncompiled version. So I guess 
its not fixed then.
