Marcel,

Yes, it's possible, but there is many points where we need to take a care :

- 1st, there is 2 way to get preview : embeded JPEG or half decoded raw image.
- 2nd, histogram is currently always computed in 16 bits color depth with RAW. 
- 3rd, preview is always in 8 bits color depth.
- 4th, editor never use half RAW decoded image but full RAW decoded image instead.

Like 8 and 16 bits color depth RAW decoding have the same auto-gamma now, and if preview != embeded JPEG, i propose :

- to always use the same bits depth everywhere to compute preview and histogram
- to use the same image to compute histogram and preview.
- to always use the same settings about RAW color depth handling everywhere.

This way will simplify all RAW cache operations and will optimize memory consumptions.
