Walter, we are looking at landing this today. If you have time for a review or any comments, it would be much appreciated.

Visually, I think it is a bi improvement. Haven't had a chance to review the code yet.

Great work Gary.
This patch switches from fixed intermadiate sizes (the removed _INTERMEDIATE_* constants) to dynamic intermadiate sizes. I think this is worth to mention in the commit message. Is in the follow up patch I'm attaching.
The new calculation in _calculate_radius_and_angle that involves a square root calculation is not trivial so I asked Gary for a comment in the code. In the follow up patch too.
The while loops try sizes 1 pixel smaller for each loop. This calls the square root calculation so I was worried about performance, but Gary said he tested and the layout time is not too much slower than
the previous.
This breaks the triangle and box layouts but by the way they are commented out in favoritesview.py .

The Home View icons are a bit more spaced apart in the spiral view in OLPC 13.1.0 os8.
I wanted to get the attached patch tracked and available for testing just in case the current size of Home view icons is seen as a release blocker for XO-4 touch hardware.
