+/*
+ * And here's the description:
+ *
+ * The PROTOCOL macros allow you to log events in frame methods. In places where
+ * logging is useful either one of the PROTOCOL(...) or PROTOCOL_ENTER(...) can
+ * be used. PROTOCOL_ENTER(...) additionally logs the leaving of a method.
+ *
+ * The PROTOCOL macros accept the following parameters:
+ * 1.   A pointer to an SwFrame (usually "this" or "rThis")
+ * 2.   The function group i.e. PROT::MakeAll. This is used to decide (inline)
+ *      whether this event shall be logged at the current time.
+ * 3.   The action, usually 0. For example DbgAction::Start indents output in the log
+ *      file and DbgAction::End stops the indentation. This allows for example
+ *      PROTOCOL_ENTER to indent at the beginning of a method and stop indenting
+ *      when leaving the method.
+ * 4.   The fourth parameter is a void pointer which allows to pass anything
+ *      which can be used in the log. A good example is PROT::Grow: this requires
+ *      a pointer to the value which defines how much to grow.
+ *
+ * The log file is called "dbg_lay.out", which is saved in the current (BIN-)
+ * directory. The file contains lines with FrameId, function group and additional
+ * information.
+ *
+ * What exactly is going to be logged, can be defined as follows:
+ * 1.   The static variable SwProtocol::nRecord contains the function groups
+ *      which shall be logged.
+ *      A value of i.e. PROT::Grow causes calls to SwFrame::Grow to be
+ *      logged; PROT::MakeAll logs the calls to xxx::MakeAll.
+ *      The PROT_XY values can be combined using binary OR, the default value
+ *      is null - no method calls are logged.
+ * 2.   The SwImplProtocol class contains a filter for frame types, only method
+ *      call of frame types which are defined there are logged.
+ *      The member nTypes can be set to values like SwFrameType::Page or SwFrameType::Section and
+ *      may be combined using binary OR. The default values is 0xFFFF - meaning
+ *      all frame types.
+ * 3.   The SwImplProtocol class contains an ArrayPointer to FrameIds which need to be
+ *      tracked. If the pointer is null, all frames will be logged; otherwise
+ *      only frames of linked from the array will be logged.
+ *
+ * Code changes are needed to start logging; either change the default of nRecord
+ * in SwProtocol::Init() or change the debugger. There are several possible
+ * places in the debugger:
+ * 1.   Set a breakpoint in SwProtocol::Init() and manipulate nRecord there, set
+ *      FrameIds accordingly then start logging during program start.
+ * 2.   Set a breakpoint before any PROTOCOL or PROTOCOL_ENTER macro during
+ *      program execution, then set the lowest bit (PROT::Init) of
+ *      SwProtocol::nRecord. This activates the function group of the following
+ *      macro and causes it to be logged in the future.
+ * 3.   There's a special case for 2: If one uses 2. in SwRootFrame::PaintSwFrame(..),
+ *      the log settings are taken from the file "dbg_lay.ini"!
+ *      In this INI-file you can have comment lines starting with a '#'.
+ *      The sections "[frmid]", "[frmtype]" and "[record]" are relevant.
+ *      In the [frmid] section, you can put FrameIds of the Frames to be logged.
+ *      If there are no entries in this section, all Frames will be logged.
+ *      In the [frmtype] section, the frame types which should be logged are
+ *      listed; default is USHRT_MAX which means that all types are logged.
+ *      It's possible to remove types from the list using '!' in front of a
+ *      value. The value !0xC000 would for example exclude SwContentFrames from
+ *      logging.
+ *      In the [record] section the functions group which should be logged are
+ *      listed; default is 0 which means that none are logged. It's also
+ *      possible to remove functions using '!'.
+ *      An example INI file:
+ *           #Functions: all(0x0007ffff), except PrintArea (0x200)
+ *           [record] 524287 !512
+ *           [frmid]
+ *           #the following FrameIds:
+ *           1 2 12 13 14 15
+ *           #no layout frames, except ColumnFrames
+ *           [frmtype] !0x3FFF 0x4
+ *
+ * As soon as the logging is in process, one can manipulate many things in
+ * SwImplProtocol::Record_(...) using a debugger, especially concerning
+ * frame types and FrameIds.

+|*      With a paragraph-anchored fly it's absolutely possible that
+|*      the anchor reacts to changes of the fly. To this reaction the fly must
+|*      certainly react too. Sadly this can lead to oscillations; for example the
+|*      fly wants to go down therefore the content can go up - this leads to a
+|*      smaller TextFrame thus the fly needs to go up again whereby the text will
+|*      get pushed down...
+|*      To avoid such oscillations, a small position stack is built. If the fly
+|*      reaches a position which it already had once, the action is stopped.
+|*      To not run into problems, the stack is designed to hold five positions.
+|*      If the stack flows over, the action is stopped too.
+|*      Cancellation leads to the situation that the fly has a bad position in
+|*      the end. In case of cancellation, the frame is set to automatic top
+|*      alignment to not trigger a 'big oscillation' when calling from outside
+|*      again.

+ * A Frame needs "normalization" if it is directly placed below a footnote boss (page/column) and its
+ * size changes. There is always a frame that takes the maximum possible space (the frame that
+ * contains the Body text) and zero or more frames which only take the space needed (header/footer
+ * area, footnote container). If one of these frames changes, the body-text-frame has to grow or
+ * shrink accordingly, even though it's fixed.
+ *
+ * !! Is it possible to do this in a generic way and not restrict it to the page and a distinct
+ * frame which takes the maximum space (controlled using the FrameSize attribute)?
+ * Problems:
+ *   - What if multiple frames taking the maximum space are placed next to each other?
+ *   - How is the maximum space calculated?
+ *   - How small can those frames become?
+ *
+ * In any case, only a certain amount of space is allowed, so we never go below a minimum value for
+ * the height of the body.
+ *
+ * @param nDiff the value around which the space has to be allocated
