USAGE:

	$.growl(title, msg);
	$.growl(title, msg, image);
	$.growl(title, msg, image, priority);

THEME/SKIN:

You can override the default look and feel by updating these objects:
$.growl.settings.displayTimeout = 4000;
$.growl.settings.noticeTemplate = ''
  + '<div>'
  + '<div style="float: right; background-image: url(my.growlTheme/normalTop.png); position: relative; width: 259px; height: 16px; margin: 0pt;"></div>'
  + '<div style="float: right; background-image: url(my.growlTheme/normalBackground.png); position: relative; display: block; color: #ffffff; font-family: Arial; font-size: 12px; line-height: 14px; width: 259px; margin: 0pt;">' 
  + '  <img style="margin: 14px; margin-top: 0px; float: left;" src="%image%" />'
  + '  <h3 style="margin: 0pt; margin-left: 77px; padding-bottom: 10px; font-size: 13px;">%title%</h3>'
  + '  <p style="margin: 0pt 14px; margin-left: 77px; font-size: 12px;">%message%</p>'
  + '</div>'
  + '<div style="float: right; background-image: url(my.growlTheme/normalBottom.png); position: relative; width: 259px; height: 16px; margin-bottom: 10px;"></div>'
  + '</div>';
$.growl.settings.noticeCss = {
  position: 'relative'
};


To change the 'dock' look, and position: 

$.growl.settings.dockTemplate = '<div></div>';
$.growl.settings.dockCss = {
    position: 'absolute',
    top: '10px',
    right: '10px',
    width: '300px'
  };
  
The dockCss will allow you to 'dock' the notifications to a specific area
on the page, such as TopRight (the default) or TopLeft, perhaps even in a
smaller area with "overflow: scroll" enabled?
