- * 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.
