Mathias Agopian f384cc3008 Fix an issue is SF that caused drawing artifacts when hwc changed mode ... we were not redrawing and/or clearing the FB properly when hwc moved a layer from/to FB to/from OVERLAY. In these cases we needed to expand the dirty region to include the layer that changed mode. Also split composeSurfaces() which was becoming quite large.
