  * \brief Anything related to Dillo %Widget styles is defined here.
  *
  * <h3>Overview</h3>
- * 
+ *
  * dw::core::style::Style provides some resources and attributes for
  * drawing widgets, as well as for parts of a widget (e.g., dw::Textblock
  * uses styles for its words). Creating a style is done by filling a
  * dw::core::style::StyleAttrs with the attributes and calling
  * dw::core::style::Style::create:
- * 
+ *
  * \code
  * dw::core::style::Style styleAttrs;
  * dw::core::style::Style *style;
  * dw::core::Layout *layout;
- * 
+ *
  * // ...
- * 
+ *
  * styleAttrs.foo = bar;
  * // etc.
  * style = dw::core::style::Style::create (&styleAttrs, layout);
  * // do something with style
  * \endcode
- * 
+ *
  * After this, the attributes of a dw::core::style::Style should not be
  * changed anymore, since styles are often shared between different
  * widgets etc. (see below). Most times, you simply copy the attributes
  * of another style (possible, since dw::core::style::Style is a sub
  * class of dw::core::style::StyleAttrs), modify them and create a new
  * style:
- * 
+ *
  * \code
  * styleAttrs = *anotherStyle;
  * styleAttrs.foo = baz;
  * style = dw::core::style::Style::create (&styleAttrs, layout);
  * \endcode
- * 
+ *
  * The dw::core::style::Font structure can be created by
  * dw::core::style::Font::create, in a similar, with
  * dw::core::style::FontAttrs, and colors by
  * dw::core::style::Color::create, passing 0xrrggbb as an
  * argument. Furthermore, there is dw::core::style::Tooltip, created by
  * dw::core::style::Tooltip::create.
- * 
+ *
  * Notice that fonts, colors and tooltips are only intended to be used in
  * conjunction with dw::core::style::Style.
- * 
- * 
+ *
+ *
  * <h3>Naming</h3>
- * 
+ *
  * dw::core::style::Style will become important for CSS, each CSS
  * attribute, which is supported by dillo, will refer to an attribute in
  * dw::core::style::Style. For this reason, the attributes in
  * dw::core::style::Style get the names from the CSS attributes, with
  * "camelCase" instead of hythens (e.g. "background-color" becomes
  * "backgroundColor").
- * 
+ *
  * However, dw::core::style::Style will be extended by some more
  * attributes, which are not defined by CSS. To distinguish them, they
  * get the prefix "x_", e.g. dw::core::style::Style::x_link.
- * 
- * 
+ *
+ *
  * <h3>Lengths and Percentages</h3>
- * 
+ *
  * dw::core::style::Length is a simple data type for lengths and
  * percentages:
- * 
+ *
  * <ul>
  * <li> A length refers to an absolute measurement. It is used to
  *      represent the HTML type %Pixels; and the CSS type \<length\>.
- * 
+ *
  *      For CSS lenghts, there are two units: (i) pixels and absolute
  *      units, which have to be converted to pixels (a pixel is, unlike
  *      in the CSS specification, treated as absolute unit), and (ii) the
  *      relative units "em" and "ex" (see below).
- * 
+ *
  * <li> A percentage refers to a value relative to another value. It is
  *      used for the HTML type %Length; (except %Pixels;), and the CSS
  *      type \<percentage\>.
- * 
+ *
  * <li> A relative length can be used in lists of HTML MultiLengths.
  * </ul>
- * 
+ *
  * Since many values in CSS may be either lengths or percentages, a
  * single type is very useful.
- * 
+ *

  * dw/style.hh). A dw::core::style::Style box looks quite similar to a
  * CSS box:
- * 
+ *
  * \image html dw-style-box-model.png
- * 
+ *
  * <h4>Background colors</h4>
- * 
+ *
  * The background color is stored in
  * dw::core::style::Style::backgroundColor, which may be NULL (the
  * background color of the parent widget is shining through).
- * 
+ *
  * For toplevel widgets, this color is set as the background color of the
  * views (dw::core::View::setBgColor), for other widgets, a filled
  * rectangle is drawn, covering the content and padding. (This is
  * compliant with CSS2, the background color of the toplevel element
  * covers the whole canvas.)
- * 
+ *
  * <h4>Drawing</h4>
- * 
+ *
  * The following methods may be useful:
- * 
+ *
  * <ul>
  * <li> dw::core::Widget::drawWidgetBox for drawing the box of a widget
  *      (typically at the beginning of the implementation of
  *      dw::core::Widget::draw), and
- * 
+ *
  * <li> dw::core::Widget::drawBox, for drawing parts of a widget (e.g.
  *      dw::Textblock::Word, which has its own dw::Textblock::Word::style).
  * </ul>
- * 
- * 
+ *
+ *
  * <h3>Notes on Memory Management</h3>
- * 
+ *
  * Memory management is done by reference counting,
  * dw::core::style::Style::create returns a pointer to
  * dw::core::style::Style with an increased reference counter, so you
  * should care about calling dw::core::style::Style::unref if it is not
  * used anymore. You do \em not need to care about the reference counters
  * of fonts and styles.

  * \sa\ref rounding-errors
- * 
+ *
  * Given two array \f$e_{i,\min}\f$ and \f$e_{i,\max}\f$, which
  * represent the column minima and maxima, and a total width \f$W\f$, \em
  * apportionment means to calculate column widths \f$w_{i}\f$, with
- * 
+ *
  * \f[e_{i,\min} \le w_{i} \le e_{i,\max}\f]
- * 
+ *
  * and
- * 
+ *
  * \f[\sum w_{i} = W\f]
- * 
+ *
  * There are different algorithms for apportionment, a simple one is
  * recommended in the HTML 4.0.1 specification
  * (http://www.w3.org/TR/REC-html40/appendix/notes.html#h-B.5.2.2):
- * 
+ *
  * \f[w_{i} = e_{i,\min} +
  *    {e_{i,\max} - e_{i,\min}\over\sum e_{i,\max} - \sum e_{i,\min}}
  *    (W - \sum e_{i,\min})\f]
- * 
+ *
  * This one is used currently, but another one will be used soon, which is
  * described below. The rest of this chapter is independant of the exact
  * apportionment algorithm.
- * 
+ *
  * When referring to the apportionment function, we will call it
  * \f$a_i (W, (e_{i,\min}), (e_{i,\min}))\f$ and write
  * something like this:
- * 
+ *
  * \f[w_{i} = a_i (W, (e_{i,\min}), (e_{i,\max})) \f]
- * 
+ *
  * It is implemented by dw::Table::apportion.
- * 
+ *
  * <h4>Column Extremes</h4>
- * 
+ *
  * \sa\ref rounding-errors
- * 
+ *
  * The sizes, which all other sizes depend on, are column extremes, which
  * define, how wide a column may be at min and at max. They are
  * calculated in the following way:
- * 
+ *
  * <ol>
  * <li> First, only cells with colspan = 1 are regarded:
- * 
+ *
  *      \f[ e_{\hbox{base},i,\min} = \max \{ e_{\hbox{cell},i,j,\min} \} \f]
  *      \f[ e_{\hbox{base},i,\max} = \max \{ e_{\hbox{cell},i,j,\max} \} \f]
- * 
+ *
  *      only for cells \f$(i, j)\f$ with colspan = 1.
- * 
+ *
  * <li> Then,
  *      \f$e_{\hbox{span},i,\min}\f$ (but not \f$e_{\hbox{span},i,\max}\f$)
  *      are calculated from cells with colspan > 1. (In the following formulas,
  *      the cell at \f$(i_1, j)\f$ always span from \f$i_1\f$ to \f$i_2\f$.)
  *      If the minimal width of the column exeeds the sum of the column minima
  *      calculated in the last step:
- * 
+ *
  *      \f[e_{\hbox{cell},i_1,j,\min} >
  *         \sum_{i=i_1}^{i=i_2} e_{\hbox{base},i,\min}\f]
- * 
+ *
  *      then the minimal width of this cell is apportioned to the columns:
- * 
+ *
  *      <ul>
  *      <li> If the minimal width of this cell also exeeds the sum of the
  *           column maxima:
- * 
+ *
  *        \f[e_{\hbox{cell},i_1,j,\min} >
  *           \sum_{i=i_1}^{i=i_2} e_{\hbox{base},i,\max}\f]
- * 
+ *
  *           then \f$e_{\hbox{cell},i_1,j,\min}\f$ is apportioned in a simple
  *           way:
- * 
+ *
  *        \f[e_{\hbox{span},i,j,\min} =
  *              e_{\hbox{base},i,\max}
  *                 {e_{\hbox{span},i,j,\min} \over
  *                  \sum_{i=i_1}^{i=i_2} e_{\hbox{base},i,\max}}\f]
- * 
+ *
  *      <li> Otherwise, the apportionment function is used:
- * 
+ *
  *        \f[e_{\hbox{span},i,j,\min} =
  *           a_i (e_{\hbox{cell},i_1,j,\min},

- * 
+ *
  * Details on differences because of styles are omitted. Below, this
  * total width is called \f$W\f$.
- * 
+ *
  * <h5>Evaluating percentages</h5>
- * 
+ *
  * The following algorithms are used to solve collisions between
  * different size specifications (absolute and percentage). Generally,
  * inherent sizes and specified absolute sizes are preferred.
- * 
+ *
  * <ol>
  * <li> First, calculate the sum of the minimal widths, for columns, where
  *      no percentage width has been specified. The difference to the total
  *      width is at max available to the columns with percentage width
  *      specifications:
- * 
+ *
  *      \f[W_{\hbox{columns}_\%,\hbox{available}} = W - \sum e_{i,\min}\f]
- * 
+ *
  *      with only those columns \f$i\f$ with no percentage width specification.
- * 
+ *
  * <li> Then, calculate the sum of the widths, which the columns with
  *      percentage width specification would allocate, when fully adhering to
  *      then:
- * 
+ *
  *      \f[W_{\hbox{columns}_\%,\hbox{best}} = W \sum w_{i,\%}\f]
- * 
+ *
  *      with only those columns \f$i\f$ with a percentage width specification.
- * 
+ *
  * <li> Two cases are distinguished:
- * 
+ *
  *      <ul>
  *      <li> \f$W_{\hbox{columns}_\%,\hbox{available}} \ge
  *             W_{\hbox{columns}_\%,\hbox{best}}\f$: In this case, the
  *           percentage widths can be used without any modification, by
  *           setting the extremes:
- * 
+ *
  *           \f[e_{i,\min} = e_{i,\max} = W w_{i,\%}\f]
- * 
+ *
  *           for only those columns \f$i\f$ with a percentage width
  *           specification.
- * 
+ *
  *      <li> \f$W_{\hbox{columns}_\%,\hbox{available}} <
  *             W_{\hbox{columns}_\%,\hbox{best}}\f$: In this case, the widths
  *           for these columns must be cut down:
- * 
+ *
  *           \f[e_{i,\min} = e_{i,\max} =
  *              w_{i,\%}
  *              {W_{\hbox{columns}_\%,\hbox{available}} \over

  *    of paragraphs.
  *
  * <h3>Signals</h3>
- * 
+ *
  * dw::Textblock uses the signals defined in
  * dw::core::Widget::LinkReceiver, related to links. The coordinates are
  * always -1.
- * 
- * 
+ *
+ *
  * <h3>Collapsing Spaces</h3>
- * 
+ *
  * The idea behind this is that every paragraph has a specific vertical
  * space around and that they are combined to one space, according to
  * rules stated below. A paragraph consists either of the lines between
  * two paragraph breaks within a dw::Textblock, or of a dw::Textblock
  * within a dw::Textblock, in a single line; the latter is used for
  * indented boxes and list items.
- * 
+ *
  * The rules:
- * 
+ *
  * <ol>
  * <li> If a paragraph is following by another, the space between them is the
  *      maximum of both box spaces:
- * 
+ *
  *      \image html dw-textblock-collapsing-spaces-1-1.png
- * 
+ *
  *       are combined like this:
- * 
+ *
  *       \image html dw-textblock-collapsing-spaces-1-2.png
- * 
+ *
  * <li> a) If one paragraph is the first paragraph within another, the upper
  *      space of these paragraphs collapse. b) The analogue is the case for the
  *      last box:
- * 
+ *
  *      \image html dw-textblock-collapsing-spaces-2-1.png
- * 
+ *
  *      If B and C are put into A, the result is:
- * 
+ *
  *      \image html dw-textblock-collapsing-spaces-2-2.png
  * </ol>
- * 
+ *
  * For achieving this, there are some features of dw::Textblock:
- * 
+ *
  * <ul>
  * <li> Consequent breaks are automatically combined, according to
  *      rule 1. See the code of dw::Textblock::addParBreak for details.
- * 
+ *
  * <li> If a break is added as the first word of the dw::Textblock within
  *      another dw::Textblock, collapsing according to rule 2a is done
  *      automatically. See the code of dw::Textblock::addParBreak.
- * 
+ *
  *  <li> To collapse spaces according to rule 2b,
  *        dw::Textblock::addParBreak::handOverBreak must be called for
  *        the \em inner widget. The HTML parser does this in
  *        Html_eventually_pop_dw.
  * </ul>
- * 
- * 
+ *
+ *
  * <h3>Collapsing Margins</h3>
- * 
+ *
  * Collapsing margins, as defined in the CSS2 specification, are,
  * supported in addition to collapsing spaces. Also, spaces and margins
  * collapse themselves. I.e., the space between two paragraphs is the
  * maximum of the space calculated as described in "Collapsing Spaces"
  * and the space calculated according to the rules for collapsing margins.
- * 
+ *
  * (This is an intermediate hybrid state, collapsing spaces are used in
  * the current version of dillo, while I implemented collapsing margins
  * for the CSS prototype and integrated it already into the main trunk. For
  * a pure CSS-based dillo, collapsing spaces will not be needed anymore, and
  * may be removed for simplicity.)
- * 
- * 
+ *
+ *
  * <h3>Some Internals</h3>
- * 
+ *
  * There are two lists, dw::Textblock::words and
  * dw::Textblock::lines. The word list is quite static; only new words
  * may be added. A word is either text, a widget, a break or an
  * anchor. Anchors are stored in the text, because it may be necessary to
  * correct the scroller positions at rewrapping.
- * 
+ *
  * Lines refer to the word list (first and last), they are completely
  * redundant, i.e., they can be rebuilt from the words. Lines can be
  * rewrapped either completely or partially (see "Incremental Resizing"
  * below). For the latter purpose, several values are accumulated in the
  * lines. See dw::Textblock::Line for details.
- * 
- * 
+ *
+ *
  * <h4>Incremental Resizing</h4>
- * 
+ *
  * dw::Textblock makes use of incremental resizing as described in \ref
  * dw-widget-sizes. The parentRef is, for children of a dw::Textblock, simply
  * the number of the line.
- * 
+ *
  * Generally, there are three cases which may change the size of the
  * widget:
- * 
+ *
  * <ul>
  * <li> The available size of the widget has changed, e.g., because the
  *      user has changed the size of the browser window. In this case,
  *      it is necessary to rewrap all the lines.
- * 
+ *
  * <li> A child widget has changed its size. In this case, only a rewrap
  *      down from the line where this widget is located is necessary.
- * 
+ *
  *      (This case is very important for tables. Tables are quite at the
  *      bottom, so that a partial rewrap is relevant. Otherwise, tables
  *      change their size quite often, so that this is necessary for a
  *      fast, non-blocking rendering)
- * 
+ *
  * <li> A word (or widget, break etc.) is added to the text block. This
  *      makes it possible to reuse the old size by simply adjusting the
  *      current width and height, so no rewrapping is necessary.
  * </ul>
- * 
+ *
  * The state of the size calculation is stored in wrapRef within
  * dw::Textblock, which has the value -1 if no rewrapping of lines
  * necessary, or otherwise the line from which a rewrap is necessary.
