Feature Freeze Exception: Animation for Grid Plugin Previews

Bug Description

Request for an FFe for a new set of animations to be added to the Grid plugin. This more closely matches the visual design for the grid plugin by expanding the grid rect when the mouse moves closer to the grid area.

INSTABILITY?

This code comes as part of a general cleanup of the Grid plugin for compiz and comes as some general animation code to the GridRectangle class that was added during this cleanup.

TESTING?

Testcases need to be added.

REGRESSION PLAN?

The animation can be turned on and off with an option, using the old code paths instead.

VISUALS

The animation can be seen at [1]

The 'indicator direction' should be set as 'from window'.

This looks like something that should wait, at the very least, until after
Beta 1.

This change brings us a lot closer to the original design, and is also a major refinement on one of the key new features that we will be showcasing in Natty. If this change is not a large instability risk it should definitely gain a ffe. Ping me on IRC if this needs to be discussed further, thx

I thnk that Sam has a branch up for review. It's low priority.

This dynamic behaviour can't be documented by screenshots, so the potential for breaking existing documentation is very low. We have a contingency plan, and reverting won't break other features, so this seems reasonably safe to me. Approved.

This bug was fixed in the package unity - 3.8.4-0ubuntu1
