* to propagate filling and resize steps upwards to the root of the tree.
* <li> A top-down sweep by recursively calling NWidgetBase::AssignSizePosition() to make the smallest sizes consistent over the entire tree, and to assign
* the top-left (\e pos_x, \e pos_y) position of each widget in the tree. This step uses \e fill_x and \e fill_y at each node in the tree to decide how to
* fill each widget towards consistent sizes.
* For generating a widget array, resize step sizes are made consistent.
* <li> A top-down sweep by recursively calling NWidgetBase::AssignSizePosition() with #ST_ARRAY or #ST_SMALLEST to make the smallest sizes consistent over
* the entire tree, and to assign the top-left (\e pos_x, \e pos_y) position of each widget in the tree. This step uses \e fill_x and \e fill_y at each
* node in the tree to decide how to fill each widget towards consistent sizes. Also the current size (\e current_x and \e current_y) is set.
* For generating a widget array (#ST_ARRAY), resize step sizes are made consistent.
* <li> After initializing the smallest size in the widget tree with #ST_SMALLEST, the tree can be resized (the current size modified) by calling
* NWidgetBase::AssignSizePosition() at the root with #ST_RESIZE and the new size of the window. For proper functioning, the new size should be the smallest
* size + a whole number of resize steps in both directions (ie you can only resize in steps of length resize_{x,y} from smallest_{x,y}).
* </ol>
* After the second step, the current size of the widgets are set to the smallest size.
*
* To resize, perform the last step with the new window size. This can be done as often as desired.
* When the smallest size of at least one widget changes, the whole procedure has to be redone from the start.
