/*

 * 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.
