// Since html isn't a page-layout language, it doesn't support page
// page breaks directly--that requires CSS2 support. But a page-break
// facility is handy, and has been requested more than once on the
// mailing lists. This wxHtml tag handler implements just enough of
// CSS2 to support a page break by recognizing only
//   <div style="page-break-before:always">
//
// wxHtml maintains page breaks in wxHtmlPrintout::m_PageBreaks. The
// tag handler below adds appropriate offsets to that array member.
// wxHtmlDCRenderer::Render() accesses that array and makes a new page
// begin after each page-break tag.

// The page-break handler does all its work in AdjustPagebreak(). For
// all tag handlers, that function adjusts the page-break position.
// For other tags, it determines whether the html element can fit on
// the remainder of the page; if it cannot fit, but must not be split,
// then the function moves the page break provided in the argument up,
// and returns 'true' to inform the caller that the argument was
// modified.
//
// Due to its special purpose, the page-break facility differs from
// other tags. It takes up no space, but it behaves as though there is
// never enough room to fit it on the remainder of the page--it always
// forces a page break. Therefore, unlike other elements that trigger
// a page break, it would never 'fit' on the following page either.
// Therefore it's necessary to compare each pagebreak candidate to the
// array wxHtmlPrintout::m_PageBreaks of pagebreaks already set, and
// set a new one only if it's not in that array.
