Drawing the blue "unread dot" on the iPhone Mail app

Question

Does anyone have an example of how to draw the blue "unread dot" used in Apple's Mail App? This one in specific: http://bit.ly/3A7XxD

Drawing an ellipse is straight forward with Quartz2d, but the subtle use of shadows+gradients make this look really 3d.

Answer 1

I think the blue dot in mail is actually an image; I would imagine that blitting an image would be faster than drawing a gradient.
