commit a8ce17de0f28f80d5ea2bf0f4acd7f8bf707f072
Author: phantomjinx <[email protected]>
Date: Sun Sep 11 00:44:09 2011 +0100
Implement drag n drop cover support for clarity
* In the same way as the coverart display, using fetchcover, a jpg can be
dragged from the browser and replace the main cover in the index.
* The dnd sends a track update signal and the tracks are all updated
accordingly.
