Damages and captures both trigger repaints of outputs. Some configurations don't care about damages and use headless only for captures. This commit adds a new feature to libweston that lets outputs repaint only on captures, not on damages. The headless backend enables that new feature when given a special refresh rate of 0 mHz.
