[PATCH] Provide damage region for screen recording on Raspberry Pi

[Tomohito Esaki]

From: Shinya Saito <ssaito at igel.co.jp>

When trying to do sceen recording using the screenshooter, no screen data
was ever processed because the rpi-renderer never set the previous frames
damage area.

Update the rpi-renderer to copy the necessary data.
