-//           Ingo Weyrich (2014-07-07)
-//              optimized the highlight protection case
-//              needs 2*width*height*sizeof(float) byte less memory than before
-//              needs about 60% less processing time than before

-// This function uses parameters:
-//      exposure (linear): 2^(-8..0..8): currently 0.5 +3
-//      preserve (log)   : 0..8 : currently 0.1 1
