1. Add support for Dynamic Resolution Change We add support for DRC on virtual displays. This is achieved by reading the width and height attributes that are set as part of the buffer handle metadata. For the WFD use cases, the WFD MultiMedia framework will update the width and height during DRC by using setMetaData API with UPDATE_BUFFER_GEOMETRY. We then proceed to configure WB with the new resolution for subsequent frames. 2. Update WB dump with output buffer format and resolution Update WB dump with output buffer format and resolution. This is helpful for debugging purposes. Change-Id: I537277499041bffc7bfc5c6e3d024b67f80fce44
