/* 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
 * CONFIG_PDCURSES_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.
