Mutter 3.10 Beta 2 Adds Support for Idle Tracking

Mutter 3.10 Beta 2 removes the man pages from deprecated utilities, adds support for idle tracking, skips CRTC reconfigurations that have no effect, ignores skip-taskbar hints on parentless dialogs, and checks event timestamps before reconfiguring. Moreover, blending is turned off when drawing entirely opaque regions, redraws are no longer queued for obscured regions, pixbuf data is no longer saved in user data, and the following bugs have been squashed: #706582, #706598, #706787, #706729, #706825, #707081, #707090, #707250, #707267.
