PDCurses Text Attributes
========================

Originally, PDCurses used a short (16 bits) for its chtype. To include
color, a number of things had to be sacrificed from the strict Unix and
System V support. The main problem was fitting all character attributes
and color into an unsigned char (all 8 bits!).

Today, PDCurses by default uses a long (32 bits) for its chtype, as in
System V. The short chtype is still available, by undefining CHTYPE_LONG
and rebuilding the library.

The following is the structure of a win->_attrs chtype:

short form:

-------------------------------------------------
|15|14|13|12|11|10| 9| 8| 7| 6| 5| 4| 3| 2| 1| 0|
-------------------------------------------------
  color number |  attrs |   character eg 'a'

The available non-color attributes are bold, reverse and blink. Others
have no effect. The high order char is an index into an array of
physical colors (defined in color.c) -- 32 foreground/background color
pairs (5 bits) plus 3 bits for other attributes.

long form:

----------------------------------------------------------------------------
|31|30|29|28|27|26|25|24|23|22|21|20|19|18|17|16|15|14|13|12|..| 3| 2| 1| 0|
----------------------------------------------------------------------------
      color number      |     modifiers         |      character eg 'a'

The available non-color attributes are bold, underline, invisible,
right-line, left-line, protect, reverse and blink. 256 color pairs (8
bits), 8 bits for other attributes, and 16 bits for character data.

   Note that there is now a "super-long" 64-bit form,  available by
defining CHTYPE_LONG to be 2:

-------------------------------------------------------------------------------
|63|62|61|60|59|..|34|33|32|31|30|29|28|..|22|21|20|19|18|17|16|..| 3| 2| 1| 0|
-------------------------------------------------------------------------------
         color number   |        modifiers      |         character eg 'a'


   We take five more bits for the character (thus allowing Unicode values
past 64K;  UTF-16 can go up to 0x10ffff,  requiring 21 bits total),  and
four more bits for attributes.  Two are currently used as A_OVERLINE and
A_STRIKEOUT;  two more are reserved for future use.  31 bits are then used
for color.  These are usually just treated as the usual palette
indices,  and range from 0 to 255.   However,  if bit 63 is
set,  the remaining 30 bits are interpreted as foreground RGB (first
fifteen bits,  five bits for each of the three channels) and background RGB
(same scheme using the remaining 15 bits.)
