Issue 2846: Filter preview through output profile when using a monitor profile.

Browse Source 
- Removed the "Rendering intent" setting from Preferences,
- Hard-code "relative colorimetric" intent everywhere,
- Filter through output profile before filtering through monitor
  profile if using a monitor profile,
- If not using a monitor profile, a direct sRGB conversion is done,
