+New Tri-state type for WMButton
+-------------------------------
+
+A new check-box type button is available with state On/Off/Tri, the later being
+generally used to express "leave as-is". The states are cycled through as user
+click on the button. It is created with:
+  btn = WMCreateButton(parent_widget, WBTTriState);
+
+There are is this case 3 possible values for WMSetButtonSelected/WMGetButtonSelected:
+ - 0 and 1, the legacy checked/unchecked states
+ - the new -1, when in the 3rd state

+Support for pixmap in the background of Widget
+----------------------------------------------
+
+The new function WMSetWidgetBackgroundPixmap was introduced to specify a pixmap
+that will be displayed as the background of a widget instead of the usual plain
+color. The dual WMGetWidgetBackgroundPixmap is provided too.

+Get the text of a button
+------------------------
+
+It was assumed that there was no need to retrieve the text from a button because
+it is generally a static constant text, but there are some cases where this can
+be useful, so the new function WMGetButtonText was added to the API.
