Romain Guy 954f9112e4 Replace generic tonemap curve with a simpler one (#5041)
* Replace generic tonemap curve with a simpler one

This change removes the shoulder parameter which had inconsistent
behaviors. The new curve is simpler and designed to still match
by default the gray point and the contrast of ACES in a bright
surround.

* Fix build
