/**
* HippoCanvasLayout:
*
* The #HippoCanvasLayout interface represents a custom layout strategy for
* the contents of a #HippoCanvasBox. The implementor is responsible for
* implementing the three basic operations get_width_request, get_height_request,
* and allocate. In each case, the layout manager should loop over all children
* returned by hippo_canvas_box_get_layout_children(), and call the corresponding
* method on #HippoCanvasBoxChild for each child. (You must do this, even
* if you aren't going to use the returned values to compute the returned values
* from get_width_request or get_height_request.)
*
* The widths, heights, and positions referenced in the method parameters are the
* widths, heights, and positions of the content area, after padding, border,
* and alignment have already been dealt with.
*
* The box that the layout manager acts upon is passed to set_box when the user
* calls hippo_canvas_box_set_layout(). set_box is called passing in %NULL when
* the box is destroyed or a different layout manager set.
*
* The implementor should store the box for future reference, but does not need
* to add an explicit reference. (If you do add an explicit reference, then there
* is some danger of a memory leak if the box is unreferenced without being
* explicitely destroyed with hippo_canvas_item_destroy().)
