Feature request: Manual image cropping with filters

[rolandschaub]

When applying a filter to an image that results in image cropping, there is currently no way to manually define the cropping area. There could be a button next to the filter dropdown with a cropping icon that opens a cropping dialog. There are a number of JavaScript libraries for this purpose:

The aspect ratio of the cropping zone would have to be fixed according to the filter settings.

we should avoid using jQuery. It must be: pure angularjs code or native javascript code.

maybe something like this? https://github.com/CrackerakiUA/ui-cropper

Yes, this looks good.

• add "edit" button in file detail
• create a copy of the file
• apply changes
• if "replace" original is select, replace the original file and remove all filter versions
