// text that needs to be redrawn so it looks fast to the user.
//
// NOTE: This blows away the current clip region so if you care, you must restore it afterwards. I
// don't do it here because you may want to make a couple of these calls in a row and restoring the
// clip rect in between would be a waste. It also blows away the background color.
