Batch jobs

[Lehonti]

The idea is being able to apply an effect, adjustment, or similar to all the files in a folder.

One of the safest and simplest (albeit rigid and limited) ways to proceed initially that I can imagine is having a dialog where the user has to:

• Choose a source folder
• Choose one or several of the supported file formats in order to filter the files from the source folder. To understand what I mean, consider that ORA would most likely not be supported initially (how would you apply an effect to an image with several layers?), so we shouldn't allow the user to think that their ORA files will be processed
• Choose a destination folder to be created. Refuse to use an existing folder

Many things would have to be changed for this to be viable, so it's probably too late to try to include this feature in the upcoming version of Pinta, but it could inform future refactoring and development efforts.

Once implemented, we would be able to change (improve!) the internal implementation liberally, as it would not be part of any public API.
