/// @brief Usage and example compilations:
/// Include this file in other source code:
/// /// #define BIOSFONT_STATICS /// In one compilation unit.
/// #include "biosfont.h.cpp"
/// Example of autonomous unit test compilation and execution.
/// g++ -Wall -W4 -O4 -DBIOSFONT_UNIT_TEST biosfont biosfont.h.cpp
/// strip biosfont
/// ./biosfont
/// This code also compiles in ordinary C (by eliminating namespacing).
/// gcc -Wall -W4 -O4 -DBIOSFONT_UNIT_TEST biosfont biosfont.h.cpp
/*****************************************************************************/
/// @brief Purpose: This file provides an absolute bitmapped graphics font.
/// This is a (slightly adjusted) iAPX86 ROM BIOS font.
/// This font supports ASCII codes 00H-FFH.
/// This code is invariant to endian issues.
/// No external resources, libraries, or calls are needed or used.
/// EBCDIC and other encodings are not supported.
/*****************************************************************************/
/// @brief File naming convention: (why *.h.cpp?)
/// Managing multiple source files can be cumbersome.
/// Files implementing very simple tables and code can be
/// entirely autonomous, making distribution/integration easy:
/// This file can be used as a pure header.
/// There is no restriction on including .cpp files as headers.
/// Using a .cpp extension enables direct unit test compilation.
/// Naming it .h.cpp is sufficiently unique to be recognized.
/// I offer this naming style for headers with built-in unit testing.
/*****************************************************************************/
/// @brief Organization:
/// This files shows a sample debug font acquisition.
/// This is followed by the magnified font.
/// This is followed by the font bitmap value table.
/// This is followed by an inline font bit accessor function.
/// This is followed by unit test functions and a main function.
/*****************************************************************************/
/// @brief Size and Technical details:
/// 256 8 x 8 bit glyphs fit into 64 bits each for a
/// memory footprint of 2KBytes both here and in BIOS.
/// Compiled unit test size including main and runtime libraries:
/// 9,216 Windows XP with gcc version 3.4.5 (mingw special)
/// Bits start at the upper left and end at the lower right.
/// US English BIOS provides ASCII 0-127 at F000:FA6E and
/// extension codes 128-255 at the address stored in 0000:007C.
/// Note: the bits of each byte have been swapped end-to-end
/// (i.e. 000100111 becomes 111001000).
/// This reduces reconstruction complexity.
/*****************************************************************************/
/// @brief How the iAPX86 ROM BIOS font was copied.
/// Early IBM PCs provided fonts burned into ROM.
