* 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 5 functions are the new programming interface.
