jQuery fadeIn/fadeOut IE cleartype glitch

When fading a html node with the .fadeIn() and .fadeOut() functions in jQuery, IE drops the windows Cleartype rendering; which results in very ugly text. This problem appears to be very common, but no one has a nice solution for the problem.

The most common way to solve this problem is by removing the filter CSS attribute. In normal javascript, it would look like this:

document.getElementById('node').style.removeAttribute('filter');

and in jQuery, it would look like this:

$('#node').fadeOut('slow', function() {
this.style.removeAttribute('filter');
});

This means that every single time we want to fade an element, we need to remove the filter attribute, which makes our code look messy.
