KSnapshot: Open in KolourPaint
Signed-off-by: Emanoil Kotsev <deloptes@gmail.com> KSnapshot: Preload screenshot in KolourPaint Fix preloading a screenshot into KolourPaint by writing data into a temporary file. When the editor closes and assuming any changes have been saved to the same temp file, the screenshot data in KSnapshot get updated, allowing to save the screenshot in the usual way. KSnapshot: Implement Open With... options using TDETrader This allows us to dynamically determine which applications can be used to open the snapshot.
