    PDC_RGB         if you want to use RGB color definitions
                    (Red = 1, Green = 2, Blue = 4) instead of BGR
    PDC_WIDE        if building / built with wide-character support
    PDC_FORCE_UTF8  if forcing use of UTF8 (implies PDC_WIDE)
    PDC_DLL_BUILD   if building / built as a Windows DLL
    PDC_NCMOUSE     to use the ncurses mouse API instead
                    of PDCurses' traditional mouse API

Text Attributes
===============

By default,  PDCurses uses 64-bit integers for its chtype.  All chtypes
have bits devoted to character data,  attribute data,  and color pair data.
There are three configurations supported :

Default, 64-bit chtype,  both wide- and 8-bit character builds:
-------------------------------------------------------------------------------
|63|62|..|53|52|..|34|33|32|31|30|29|28|..|22|21|20|19|18|17|16|..| 3| 2| 1| 0|
-------------------------------------------------------------------------------
  unused    |color pair |        modifiers      |         character eg 'a'

   21 character bits (0-20),  enough for full Unicode coverage
   12 attribute bits (21-32)
   20 color pair bits (33-52),  enough for 1048576 color pairs
   11 currently unused bits (53-63)

32-bit chtypes with wide characters (CHTYPE_32 and PDC_WIDE are #defined):
    +--------------------------------------------------------------------+
    |31|30|29|28|27|26|25|24|23|22|21|20|19|18|17|16|15|14|13|..| 2| 1| 0|
    +--------------------------------------------------------------------+
          color pair        |     modifiers         |   character eg 'a'
   16 character bits (0-16),  enough for BMP (Unicode below 64K)
   8 attribute bits (16-23)
   8 color pair bits (24-31),  for 256 color pairs

32-bit chtypes with narrow characters (CHTYPE_32 #defined,  PDC_WIDE is not):
    +--------------------------------------------------------------------+
    |31|30|29|28|..|22|21|20|19|18|17|16|..|12|11|10| 9| 8| 7| 6|..| 1| 0|
    +--------------------------------------------------------------------+
          color pair        |     modifiers               |character
   8 character bits (0-7);  only 8-bit charsets will work
   12 attribute bits (8-19)
   12 color pair bits (20-31),  for 4096 pairs

All attribute modifier schemes include eight "basic" bits:  bold, underline,
right-line, left-line, italic, reverse and blink attributes,  plus the
alternate character set indicator. For default and 32-bit narrow builds,
three more bits are used for overlined, dimmed, and strikeout attributes;
a fourth bit is reserved.

Default chtypes have enough character bits to support the full range of
Unicode,  all attributes,  and 2^20 = 1048576 color pairs.  Note,  though,
that as of 2022 Jun 17,  only WinGUI,  VT,  X11,  Linux framebuffer,  and
SDLn have COLOR_PAIRS = 1048576.  Other platforms (DOSVGA,  Plan9, WinCon)
may join them.  Some (DOS,  OS/2) simply do not have full-color
capability.
