* Functions for window front/back management.
* These might only be necessary for MacOS.
*
* One problem is that the PIKA and the scriptfu extension process are separate "apps".
* Closing a main scriptfu dialog does not terminate the scriptfu extension process,
* and MacOS does not then activate some other app.
* On other platforms, the select dialogs are transient to the PIKA app's progress bar,
* but that doesn't seem to work on MacOS.
*
* Also some of the PIKA "select" widgets (for brush, pattern, gradient, font, palette)
* for plugins are independent and tool like:
* their popup dialog window is not a child of the button which pops it up.
* The button "owns" the popup but GDK is not aware of that relation,
* and so does not handle closing automatically.
* There are PDB callbacks in each direction:
* from the select dialog to the scriptfu extension on user's new selection
* from the scriptfu extension to the select dialog on closing
*
* This might change in the future.
* 1) in PIKA 3, scriptfu and python plugins should use a common API for a control dialog,
* (script-fu-interface.c is obsoleted?)
* 2) the code for select dialogs is significantly changed in PIKA 3
* 3) Gtk3 might solve this (now using Gtk2.)
