paragraph(content, key, value, ..., key, value)
Layout content horizontally like in a XHTML p.
Content is either a single content object such as a string or a list of content objects. In the latter case, special syntax content(content, ..., content) must be used.
Key, value, ..., key, value specify optional style parameters.
Example:
paragraph(content(icon(right), "generated content", icon(left)),
border-width, 1,
border-style, solid)
