Subject: [PATCH 8/9] Random pixels betwen OSD and bars (#824)

* Support background color changes
 - pf/background used to change background color once per line
   resulting in higher visual quality.

* - blank out left/right sides
  based on kernel modifications by Thomas Jentzch
  work in progress, stray pixel remaining

* MovieCart: Fixed delayed right side kernel

* MovieCart: Fixed random pixels between OSD + bars
