/*
  show_2numeric_input allows to invoke a 2 numeric input popup.

  show_2numeric_input compared to _show_2NumericInput avoids 
  manipulations of utf16 strings.
  It returns 1 if OK, 0 if Cancelled

  Values like -1 or 0 for min_values will cancel the popup.
  Otherwise, you can have negative intervals (but not using -1 or 0)

  How to use:
   const char * title = "Title";
   const char * subtitle = "Sub Title";
   const char * msg1 = "Element 1";
   const char * msg2 = "Element 2";
   int value1 = 7;
   int value2 = 42;
   int result = show_2numeric_input(title, subtitle, msg1, &value1, 1, 42, msg2, &value2, -42, 9001);
   printf("%d(%s) : %d; %d\n", result, (result == 1)?"OK":"CANCELLED", value1, value2);
