 Absolute and fixed positiones
 =============================
 
-If you look at dw::OutOfFlowMgr in detail, you will find that some
-work on **absolute positions** has already be done, but is
-deactivated. Absolutely positioned elements will also be handled by
-dw::OutOfFlowMgr, in a way transparent to dw::Textblock. Positioning
-is much simpler than for floats: the complicated relation between
-dw::Textblock and dw::OutOfFlowMgr (calculation of the vertical
-position of floats on one hand, limiting line widths by floats on the
-other hand) does not occur here.
-
-Since handling sizes becomes an important part for absolute positions,
-the full implementation will be realized after finishing the planned
-redesign of widget sizes (see \ref dw-grows).
-
-(One note already about the *z-index* attribute: different blocks,
-represented by widgets, may overlap; *z-index* has an influence the
-order in which
-
-1. widgets are drawn (in *ascending* order of *z-index*), and
-2. mouse events are deligated to the widgets (in *descending* oder of
-   *z-index*).
-
-Something similar is already done for floats: effectively, floats have
-a larger *z-index* than the textblocks in flow. (See *end* of
-dw::Textblock::draw and *beginning* of
-dw::Textblock::getWidgetAtPoint.)
-
-For a complete implementation, handling *z-index* becomes a bit more
-complicated. An idea is to keep track of the minimum and maximum value
-of *z-index*, and then iterating over all possible values (ascending
-for drawing, descending for event handling), handling only widgets
-with a specific *z-index* in one iteration.)
-
-There are currently no plans for an implementation of **fixed
-positions** soon. These problems have to be considered:
-
-- Generally attaching dillo widgets to the viewport, not the canvas;
-  this is also required for the implementation of
-  *background-attachment*, see \ref dw-images-and-backgrounds.
-- To which containing block are elements with fixed position related?
-  To the same as floats and absolutely positioned?
+To be documented.
