Rather than just have a single Refresh method that gets called whenever something happens that could possibly be of interest to the visual tools, add seperate methods for signaling frame number changes and changes to the file, and use the new SelectionController stuff for other things that used to merit a Refresh. This eliminates a large amount of redundant reparsing of lines which happened on paint, as well as a large number of redundant repaints. Frame data is now only uploaded to the video card when the frame number changes rather than when anything at all changes, slightly improving performance when using mesa's software opengl implementation. Vector clip and drag tools now do a slightly better job of not discarding the user's selection for no apparent reason, and strange selection behavior from clicking on visual features should now be entirely fixed. Everything but the constructor and toolbar event handler in the visual tool implementations are now private. Originally committed to SVN as r4631.
