Patch against layout manager branch.

Some more API.

Proposed API for CcItem:

virtual void cc_item_get_children_bounds (CcItem *self, CcView *view, CcDRect *bounds)
virtual void cc_item_get_natural_size (CcItem *self, gdouble *width, gdouble *height)
virtual void cc_item_get_minimum_size (CcItem *self, gdouble *width, gdouble *height)
virtual CcLayoutFlags cc_item_get_layout_flags (CcItem *self, gdouble *width, gdouble *height)
virtual gdouble cc_item_get_height_for_width (CcItem *self, gdouble width)
virtual gdouble cc_item_get_width_for_height (CcItem *self, gdouble height)
virtual void cc_item_set_bounds (CcItem *self, CcView *view, CcDRect *bounds)

void cc_item_mark_bounds_dirty (CcItem *self, CcView *view)
void cc_item_mark_all_bounds_dirty (CcItem *self)

Proposed API for CcLayout:

virtual void cc_layout_get_natural_size (CcLayout *self, gdouble *width, gdouble *height)
virtual void cc_layout_get_minimum_size (CcLayout *self, gdouble *width, gdouble *height)
virtual CcLayoutFlags cc_layout_get_layout_flags (CcLayout *self, gdouble *width, gdouble *height)
virtual gdouble cc_layout_get_height_for_width (CcLayout *self, gdouble width)
virtual gdouble cc_layout_get_width_for_height (CcLayout *self, gdouble height)

virtual void cc_layout_set_bounds (CcLayout *self, CcView *view)
virtual void cc_layout_mark_bounds_dirty (CcLayout *self, CcItem *child, CcView *view)

I think we should work together with Matthias who's currently implementing a new size negotioation mechanism in GTK+.

Criawips  development has been stalled and it has been unmaintained for a few years now. Maintainers don't have future development plan so i am closing bugs as WONTFIX. Please feel free to reopen the bugs in future if anyone takes the responsibility for active development.
