Review request for Plasma.


Summary
-------

Remember the background image used for the tray-icon, and do not update it if it has not changed.

The following XClearArea call leads to a very annoying flicker when the backing-store is disabled, and to the user, it happens at totally random occasions.

Unfortunately this can only be implemented cheaply for the raster engine, since there does not seem to be an efficient way to compare QPixmap's.
