------- Additional Comments from Jocelyn Turcotte <jocelyn.turcotte at nokia.com>
I thought that drawsContent() was also true when we had a directly composited
image.
- Cleared the backing stores in setDrawsContent(false)
- Moved the early return for if not drawsContent under the image case in
updateContentsBuffers
- Removed the check for drawsContent in tiledBackingStoreContentsRect since we
won't have a backing store in that case
