Instead of changing the display order of the Folder to preserve
the upper left quadrant, we are opting to change the Folder Icon
preview to always show the upper left quadrant.
This means that when adding items to a Folder, the preview items
may change. (They will change when the column size increases).

The goal is to eventually move all of the PreviewBackground and
Preview Item drawing out of the FolderIcon class.

without going through the child'draw pass.
Also simplifying the draw code for the FolderIcon to remove any cycling invalidate calls

This class verifies whether an item in a Foder is displayed in
the FolderIcon preview, based on the item's rank.
We use this class to determine which items in a Folder will be
displayed in the preview.

-> When there is disparity between the cached icon size and the available space
in the preview, the folder preview could appear not as intended (either
overly crammed, or overly spacious)

-> Refactored the preview background rendering to be much more self-contained.
This cleans up a lot of code in the CellLayout, and keeps the logic in the
right place.
-> We switch to software rendering for performance and compatibility reasons.
-> Removed all assets.
-> FolderIcon accept animation includes animation of the clipped region.
-> 1:1 hand-off of drawing of the FolderIcon background between the FolderIcon
and the CellLayout. Unfortunately, CellLayout rendering is still required
to work around clipping issues (due to use of software layer). We also
need this to support folder creation feedback.

-> Tracking individual drawing parms for each item
-> This enables animation of the preview items as the preview changes
Change-Id: I1b8f650cb28dc09cfb921bbdc93f2a3db61178fd
-> Modeled as a set of items around a circle
-> Modulate the radius and icon size as number of items grow
-> Clip the icons by a circular clip aligned to the background drawable
Remaining issues
-> Probably want to move to a programmaticly drawn circle + shadow
-> Anti-aliasing of the clipped region will need more attention
-> Need to animate all items in the preview as it changes (this
wasn't required before)
