Spread - Scaling all the windows is too slow

[Marco Trevisan (Treviño)]

Since the support for the unity-decorated windows on spread, when hitting Super+W to spread all the windows, is a lot more slow.

Some drawing caching is needed.

If anyone still has complains about scale performance after this fix is released, see bug 1039942.
