#1748954 (New status bar fades into all white background): FrameLayout wasn't updating its foreground drawable when its padding changed, which would happen as the status bar is shown and hidden. To fix this I also ended up fixing a problem in the view debug stuff where we couldn't get a bitmap for a view that is the full screen size because it is too big... actually I just went ahead and added another function to snapshot the view hierarchy which works a lot better for us anyway.
#1737952 (Home screen icons overlap with the notification bar after exiting any camera app): Originally I punted this because it only happened in rare situations, but now that home is always portrait it happens a lot more so it is more important to fix. This involved a few things to clean up hiding/showing the status bar:
- We now determine when to hide and show it during layout, which allows us to do this at the time it is actually needed rather than during animation after we can actually catch it for the initial display of a window. This required tweaking the layout API so the policy can request a second layout pass if needed.
- When doing layout, we are now much more aggressive about skipping the layout of windows. Basically anything that we know will be hidden in the near future is ignored for layout, so that it doesn't glitch as it is transfered out of the screen. The theory being that it is better to leave it as it was originally placed while we are transitioning it out, than to switch it to something slightly more correct.

Also do most of the work for issue #1732012 (Only show screen rotation animation when triggered by sensor). This just needs to be hooked up to the surface flinger API when that appears.

Define orientation limits for various cases.
Values between 235 and 295 are considered landscape,
0 - 60 are considered portrait.
0-235 are ignored since we don't support Surfaces for 180 and 270 yet.
A linear threshold value is calculated for values between 265 and 355 to switch between landscape and portrait.(different for both cases)
Based on current mode we not only calculate the threshold but also compare accordingly based on increasing or decreasing orientation
