RPI, config.txt: overscan, not working

[Ian Lepore]

While searching for something else I just ran across this info:

        overscan_scale=1 caused the output of openFrameworks to respect
        the overscan_left, overscan_right, top and bottom settings with
        the use of an LCD display connected via composite.

So maybe just adding that to config.txt would make your overscan
settings work right.  I found that at:
