Will be used for variants with custom non-rectangular board (Hex, at least)
Or, with other board shapes (see greenchess.net for example)
-Would be nice to display some better variants names (Pacosako -> Paco-Ŝako etc),
-but the "formatted" name with uppercase + all lower cases would still be required.
-(For example in variants list, or tournament variant field).
+Merge variants 1, 2 (3) into one with sub-variant selection when starting a game (New Game + vs engine + analyse)
+E.g. Checkered 1 & 2 into one, and so on.
+Need additional field in variant code... in a generic way (radiobutton or select or checkbox?)
+#New variants:
Chessplode
Tablut

+CWDA : need game options (also useful at least for Monster)
