Comment (by koopersmith):

 As [https://irclogs.wordpress.org/chanlog.php?channel=wordpress-
 ui&day=2012-08-28&sort=asc#m54149 discussed in IRC], I think the best
 option for moving forward is using a PNG rotated using CSS3 animations, as
 outlined in lessbloat's
 [http://core.trac.wordpress.org/ticket/21456#comment:8 earlier comment].
 We can override the background-image to use a GIF in browsers that don't
 support CSS3 animations.

 Benefits of using a rotating PNG:
 * More granular control over transparency.
 * We don't have to matte the spinner based on the background, which makes
 the spinner far more flexible.
 * Low CPU usage.
 * Rendering bugs are less likely to occur.
