+ * GtkProgress/GtkProgressBar had serious problems in GTK 1.2.
+ * 
+ *  - Only 3 or 4 functions are really needed for 95% of progress  
+ *    interfaces; GtkProgress[Bar] had about 25 functions, and 
+ *    didn't even include these 3 or 4.
+ *  - In activity mode, the API involves setting the adjustment 
+ *    to any random value, just to have the side effect of 
+ *    calling the progress bar update function - the adjustment
+ *    is totally ignored in activity mode
+ *  - You set the activity step as a pixel value, which means to 
+ *    set the activity step you basically need to connect to 
+ *    size_allocate
+ *  - There are ctree_set_expander_style()-functions, to randomly 
+ *    change look-and-feel for no good reason
+ *  - The split between GtkProgress and GtkProgressBar makes no sense 
+ *    to me whatsoever.
+ *  
+ * This was a big wart on GTK and made people waste lots of time,
+ * both learning and using the interface.
+ * 
+ * So, I have added what I feel is the correct API, and marked all the
+ * rest deprecated. However, the changes are 100% backward-compatible and
+ * should break no existing code.
+ *
+ * The following 9 functions are the new programming interface.
