/*
* We switched from an animated GIF to a JavaScript-based spinner due to a number of benefits.
* First, IE stops animating all GIFs when a request is made, even with the latest version. They do not believe this is a bug.
* Firefox stops animating GIFs in other situations, such as when we hide the processing dialog when the user wants to attempt
* the request again.
* In both of the above situations, there are a number of convoluted hacks that fix the problem in some situations, but not all. One example is
* enumerating the images in the document in JavaScript and setting the src attribute to the value of the src attribute.
* The above problems still exist even if you use CSS to display the image, using the background-image style.
* An alternate situation may be to use a PNG and use CSS3 animations to rotate the image, making it spin. However browser support still
* isn't solid for CSS3 animations, such as all IE versions before IE10.
* Another point against images is that you have to prevent dragging and disable selection, to make the interface look more professional.
* Spin.js also has the benefit of being fully compatible with all browsers across the board.
