well FIRST - i think saving a png with a gamma of anything other than the
default is just wrong. fix your display gamma - and then keep your data with
linear values. so i see that as a "no-no" secondly... then it just becomes a
output issue for the DAC :)

i alreayd do! :)

well i'd like to provide a nice way of a user doing this sanely - ie with a gui,
sliders etc... :)
