-/* scrolled window policy and size requisition handling:
- *
- * gtk size requisition works as follows:
- *   a widget upon size-request reports the width and height that it finds
- *   to be best suited to display its contents, including children.
- *   the width and/or height reported from a widget upon size requisition
- *   may be overidden by the user by specifying a width and/or height
- *   other than 0 through gtk_widget_set_usize().
- *
- * a scrolled window needs (for imlementing all three policy types) to
- * request its width and height based on two different rationales.
- * 1)   the user wants the scrolled window to just fit into the space
- *      that it gets allocated for a specifc dimension.
- * 1.1) this does not apply if the user specified a concrete value
- *      value for that specific dimension by either specifying usize for the
- *      scrolled window or for its child.
- * 2)   the user wants the scrolled window to take as much space up as
- *      is desired by the child for a specifc dimension (i.e. POLICY_NEVER).
- *
- * also, kinda obvious:
- * 3)   a user would certainly not have choosen a scrolled window as a container
- *      for the child, if the resulting allocation takes up more space than the
- *      child would have allocated without the scrolled window.
- *
- * conclusions:
- * A) from 1) follows: the scrolled window shouldn't request more space for a
- *    specifc dimension than is required at minimum.
- * B) from 1.1) follows: the requisition may be overidden by usize of the scrolled
- *    window (done automatically) or by usize of the child (needs to be checked).
- * C) from 2) follows: for POLICY_NEVER, the scrolled window simply reports the
- *    child's dimension.
- * D) from 3) follows: the scrolled window child's minimum width and minimum height
- *    under A) at least correspond to the space taken up by its scrollbars.
