UnityScreen: only redraw parts of the screen visible in each output
We draw only the parts of the screen that are visible in each output (monitor) because compiz draws things per output anyway. Speeds up the drawing by about N times, where N is the number of monitors because:
We used to draw all monitors' content when 1 monitor was rendered (=> we rendered N times the N monitors' content). Now, we draw only the current monitor's content (we render 1 time each of the N monitors' content).
Description of the change
Fix for multi-monitor:
We draw only the parts of the screen that are visible in each output (monitor) because compiz draws things per output anyway. Speeds up the drawing by about N times, where N is the number of monitors because:
We used to draw all monitors' content when 1 monitor was rendered (=> we rendered N times the N monitors' content). Now, we draw only the current monitor's content (we render 1 time each of the N monitors' content).
Works fine here.
