use separate variable for backlight animator value 

using e_bl_val here is wrong now since this needs to calculate against the starting and ending backlight values, neither of which are represented accurately by e_bl_val in some cases.

this fixes the gradually decaying backlight which occurs over repeated screen blanks

probably fixes T1152
