1. Add hook to dump the layers going to VDS based virtual display. 2. Furthermore, add utility function to dump the frame buffer and WB output buffer. This will be enabled via a system property debug.hwc.enable_vds_dump Once dumping is enabled, the dumps can be extracted from /data/vds.fb.FORMAT.XRESxYRES.raw /data/vds.wb.FORMAT.XRESxYRES.raw e.g. vds.fb.MDP_RGBA_8888.1152x1920.raw Change-Id: I2435c5507961a52929411206892c005492d5c193
