- Better `figure` and `informalfigure` rendering:

  - Caption and title are printed separately, in a consistent way.

  - Default image scaling is possible.

- Better `programlisting` and `screen` rendering:

  - All the attributes are supported

  - A default verbatim layout is provided. The text is put in a framed box with a yellow background color.

  - Long lines are wrapped.

- Minor improvements:

  - A breakline is forced after a `term` when it is immediately followed by a list.

- the following parameters are added:

  imagedata.default.scale

    It defines the default scaling rule to apply on every `imagedata` that contains no scaling attribute.

    By default the parameter is set to 'pagebound', that is the images keep their natural size up to the page boundaries.

  figure.title.top

    Set to 1 it specifies to put the title above the image. By default it is set to 0 (title below).

    This parameter has no effect if an explicit float style is used for the figures (e.g. ruled style), since the title position is then fixed by the chosen style.

  mediaobject.caption.style

    Font style applied to the caption text. Default is slanted.

  literal.width.ignore

    Set to 1 the programlisting and screen width attribute is ignored.

  literal.layout.options

    Overwrite the default verbatim layout options.

  seg.item.separator

    Defines the separator to use between several `segitem`s.

- Some bug fixes.
