// [HGM] Some remarks about the generic dialog creator of XBoard:
// GenericPopUp is needed to create a dialog from the lists of options supplied by the engines.
// But once it is there, it provides a very easy way for creating other settings dialogs as well,
// by letting XBoard provide its own, compiled-in lists of XBoard options (located in dialogs.c).
// The Option struct uses the following fields (E = for engine options, X = for XBoard options):
// Option types | XBoard-only ->
// TYPE NAME spin check string combo button box label list graph menu break end
// int value E E (h) X/E [w] (h) (h)
// int min X/E (2) (3) (1) (1) (1) (1) (3) (1) (4)
// int max X/E (w) (w) (w) (w) (w) (w) (w) (w)
// void* handle X/E X/E X/E X/E X/E X X X X X
// void* target X X X X/C C X X C C
// char* textValue X/E X/E *
// char ** choice C X/E * X
// enum type X/E X/E X/E X/E X X X X X X X X
// char * name X/E X/E X/E X/E X X X X X
// char ** font X X X X (GTK only)
// File and Path options are like String (but get a browse button added in the dialog), and Slider
// is like Spin. Menu can be PopUp or PopDown; both need the COMBO_CALLBACK bit (3) set!
// (h) or (w) means the field optionally (when non-null) specifies the height or width of the main
// control element (excluding accompanying description texts). [w] means the width is written there.
// C specifies the 'target' is a user-supplied callback function, which will be executed when the
// option is exercised.
