The --bugreport option adds two visible features: (1) a timestamp
overlay that (mostly) matches logcat, making it easier to match what
appears in the video with what's in the log, and (2) an "info page"
at the start of the video that shows the system configuration.
Enabling this option adds an additional composition step,
increasing the overhead of screenrecord. Depending on the device
and circumstances, this may be unnoticeable or very pronounced.
If --bugreport is not enabled, the overhead of screenrecord is
unchanged.
We also now track device orientation changes. This is currently
detected by polling surfaceflinger, which is suboptimal. As a
result, we detect the rotation too late, and get a weird mixed
frame before the start of the animation for 90-degree changes.
Also, allow the bit rate to be specified as e.g. "4M" for 4Mbps.
Also, --rotate is now deprecated.
