Improvements:
- Cleanup of default options files to use OS font by default
- Comments updates
- Simplify font size management as Pango/Gtk directly manage pt/px conversions
Bug fix:
- If Preference panel is closed by "cancel", font size was not reinitialized to previously saved one
- Font size was specified in "RawTherapee.css" theme and so user choice could be ignored
Disabled by default as .ori extension might be
used to identify a file as "original".
When shooting Olympus High Res files the camera
saves the High Res file as .orf and the first
of the 8 frames as .ori.
The .ori can later be used to fix artefacts from
motion or as a backup if the whole High Res came
out flawed.
