Do full layer recording in slimming paint mode
Do full layer recording in slimming paint mode

For now blink side slimming paint code doesn't support incremental
paint. Also in the future with display item caching, incremental
paint might become not more superior than full layer recording.

We should measure performance and determine the best choice. Old
incremental painting code is still kept in this CL.
