/**
* FixRowBrightnessProtect2
* Usage: FixRowBrighnessProtect2(row, adj_val, prot_val) - prot_val can be left out
* and the default of 16 will be used.
*
* row is the row you want to work on.
*
* adj_val should be a number x where -100 < x > 100. This parameter decides
* how much the brightness should be affected. Numbers below 0 will make it darker
* and number above 0 will make it brighter.
*
* prot_val is the protect value. This is what makes it behave differently than the
* normal FixBrightness. Any luma above (255-prot_val) will not be affected which is
* the basic idea of the protect script.
