Handle file dropping in editor
Provide a plugin to detect desktop file dropping into editor, for those support browsers.
The detected file info could be used to upload the file immediately or perform any possible customization.
Edit:
Yes that is most correct. Editor should have at least a hook for implementing drag&drop into editor. What I mean is that if editor is connected with file uploader (like CKFinder) it should prepare image information that uploader can use to upload file. After file is uploaded, uploader should send new image path and editor should apply it.
The patch introduces the 'dropfile' plugin, currently detect only dropped image file and fire a 'dropDesktopImage' event, which was later consumed by 'image' plugin to trigger an upload dialog.
