Make Claws glyph available in non-Chu variants
The variant-dependent replacement glyphs for promotable pieces in Chu
are now assigned to pieces that reuse the replaced glyphs to represent
promoted pieces, rather than to unused promoted pieces. This means that
in Chu they now must be replaced by swapping, which avoids occurrence
of duplicats both in Chu and other variants. And thus frees piece types
that now can be used for new glyphs. As a result the Nightrider remains
available in Chu, and the Claw glyph in other variants. Other freed
pieces are for now used for the promotion Golds of variant shogi.

The image for the Grasshopper has a copy in the Chu-promoted series.
The unpromoted image (not needed in Chu) is now preferentially taken

Any piece between Grasshopper and chu-promoted Marhall can now in principle

Double moves can now be encoded in a Polyglot es promoType = 2, and

HandleMachineMove had to be adapted to handle the two legs coming as one,
but otherwise the book code can just send the retrieved line directly
to the engine.
For Edit Book the format has to be converted to TSA-like for display,
to make the move parser that will read it on saving understand the move

The piece ID can now be suffixed with an 'ornament', which then
is considered part of the piece ID. This expands the number of pieces
that can be indicated in FEN or SAN to several times the alphabet.
This does not yet work in a promotion suffix, as it is mainly intended
for the large Shogi variants, which only use + as promotion suffix.
It also does not work on King (which deserves an unadulterated letter).
Currently the ornaments ' (single quote) and ! (exclamation point) are
defined, (through a macro SUFFIXES in moves.h), increasing the number
of piece types that can be represented to 78.

Change book Zobrist key for Chu promoted pieces
Promoted pieces for Chu (i.e. above Lion, with the exception of King)
now get keys derived from their base type, by XORing in a square-dependent

with new pieces without altering the keys for the promoted pieces.
So that the current book code works upto 48 unpromoted piece types,
rather than 48 piece types total.

Fix deselection of piece
The patch to allow entering of friendly capture (intended as a kludge
for entering non-standard castling) had broken the ability to change
the selected piece by clicking another piece, as this was now always
interpreted as a friendly capture (which was then rejected as illegal).
By testing marker[][] in stead of legal[][] this can be avoided; legal[][]
was not a good measure, because in absence of a highlight command it
is completely filled with 1, to make everything legal. No friendly squares
will ever get marked unless a highlight command does it, though.

An underscore in the menu text should not be counted when deciding where

Castle with nearest rather than corner piece
An oversized sideway King step is recognized as castling, but instead
of using the piece closest to the board edge on that rank (ignoring dark
squares) we now use the piece that the King is looking at in that direction.
This fixes castling in Omega Chess.

H.G.Muller [Thu, 5 Feb 2015 18:34:32 +0000]
Recognize castling double-moves from engine
An engine could already send double-moves of the Alien protocol,
where the same piece moved twice, which were then glued into a single
step, with the intermediate square as trampled piece. Now when the
second leg is whith a different piece, it keeps the first leg as overall
move, and tramples the second mover. This translates castlings sent
as two-piece moves to the kludge format of trampling the own 'Rook'.

<Esc> in the input field of the ICS Interaction window transfers focus

typing something in the input field. <Esc> now does that. Unlike typing
printables, it does not close the chat pane, though. In addition, <Esc>
when the chat pane is open now also transfers focus to the board, rather
than closing the chat pane. This makes quick transparent switching between
board and Chat / ICS Interaction possible. It is no longer possible to
simply hide the chat pane, though. But this was usually done for typing
a command, and swicthing to the board with <Esc> and typing the command
there has the same effect.

The Betza move generator allows castlings to be specified on non-royal
pieces, and indeed the Omega-Chess 'guarding' castles Q with R. To
prevent ambiguity this is implemented as a two-leg move QxR-s (with 's'
the target square specified in the O atom). This automatically takes care
of removal of the 'Rook', so that in ApplyMove() we only have to put it
back on the proper side of the 'King'.

Also set e.p. rights on move of Lance
The Lance is intended as Pawn alternative (because of its slim shape),
except in Superchess (where it represents Amazon) and Chu. (In regular

be logical to also make its double-Pushes set e.p. rights. Except in
Spartan Chess, which has no e.p. capture.

Some variants (like Omega Chess) have an initial triple-Push on Pawns,
wich can then e.p.-captured on both of the squares they skip. To allow
the Betza move generator to supply such e.p. captures, a bit flag is
kludged into the EP_RANK state indicator on triple pushes, while the
main value there is that of the rank directly behind the pushed Pawn.
The Betza generator then also matches the square behind it with the
e.p.-capture to-square when the falg is set.
ApplyMove() also had to be adapted, to remove the Pawn two squares
behind the capturing one, rather than straight behind it, when this
flag is set.

Make the promotion zone always 3 deep in Elven Chess
The promotion zone in Eleven Chess was treated as in Shogi, and set
to the board height divided by 3. It is better to always make it 3.
This only makes a difference when the boardHeight is overruled,
but Elven Chess is a very useful parent variant when a 3-deep promotion
zone is needed. (Makruk would only allow promotion to Ferz, and Grand
Chess would need holdings and allow only promotion to captured pieces.)

Locate corner piece in presence of DarkSquares
The 'Rook' move implied by a castling indicated through an obver-sized
King step uses the corner pieces. But the corner isn't necessarily
the edge file if the board is not rectangular, but irregularly shaped
like in Omega Chess. So we have to ignore the DarkSquares, which are
not caounted as belonging to the board.
