* Determine if a page break is allowed before $frame
* http://www.w3.org/TR/CSS21/page.html#allowed-page-breaks
*
* In the normal flow, page breaks can occur at the following places:
*
* 1. In the vertical margin between block boxes. When an
* unforced page break occurs here, the used values of the
* relevant 'margin-top' and 'margin-bottom' properties are set
* to '0'. When a forced page break occurs here, the used value
* of the relevant 'margin-bottom' property is set to '0'; the
* relevant 'margin-top' used value may either be set to '0' or
* retained.
* 2. Between line boxes inside a block container box.
* 3. Between the content edge of a block container box and the
* outer edges of its child content (margin edges of block-level
* children or line box edges for inline-level children) if there
* is a (non-zero) gap between them.
*
* These breaks are subject to the following rules:
*
* * Rule A: Breaking at (1) is allowed only if the
* 'page-break-after' and 'page-break-before' properties of all
* the elements generating boxes that meet at this margin allow
* it, which is when at least one of them has the value
* 'always', 'left', or 'right', or when all of them are 'auto'.
*
* * Rule B: However, if all of them are 'auto' and a common
* ancestor of all the elements has a 'page-break-inside' value
* of 'avoid', then breaking here is not allowed.
*
* * Rule C: Breaking at (2) is allowed only if the number of line
* boxes between the break and the start of the enclosing block
* box is the value of 'orphans' or more, and the number of line
* boxes between the break and the end of the box is the value
* of 'widows' or more.
*
* * Rule D: In addition, breaking at (2) or (3) is allowed only
* if the 'page-break-inside' property of the element and all
* its ancestors is 'auto'.
*
* If the above does not provide enough break points to keep content
* from overflowing the page boxes, then rules A, B and D are
* dropped in order to find additional breakpoints.
*
* If that still does not lead to sufficient break points, rule C is
* dropped as well, to find still more break points.
*
* We also allow breaks between table rows.
*
* @param AbstractFrameDecorator $frame the frame to check
*
* @return bool true if a break is allowed, false otherwise
