With help of Tanoku tooltips were switched from widgets to dialogs which helped to fix nasty bug with background not being restored. Although it is basically a hack around inconsistent font backbuffering in our GUI code, for the time being it is feasible. The patch was extended with way to specify tooltip background in the theme file. svn-id: r51217
