Notes

1. The existing "image-position" GTK+ property -- normally only applicable to stock buttons -- has been extended to apply to all Gtkdialog buttons.

2. Theme icons default to 20 and do not scale or refresh (the height or width directives can be used to request a size).

3. Stock icons default to GTK_ICON_SIZE_BUTTON and do not scale or refresh (the "icon-size" tag attribute can be used to adjust the size).
