*  allfont.c -- module to display the result of enumerating all fonts.
*   Includes the window procedure and an initialization routine.
*
*  There are actually two windows serviced by this module.  One for the
*   display fonts, one for the printer fonts.
*
*
*  Data structure:
*   Since we keep a modest amount of data for each possible font, and
*   since the amount of this information is known only at run time,
*   the main data structure used here is all allocated dynamically.
*   parFonts points to an array of ARFONT structures.  These structures
*   store two int's and then three pointers to arrays of LOGFONT,
*   TEXTMETRIC, and int's respectively.
*

*
*
*   So, to get the FontType of the 4th font within the 2nd family use:
*    parFonts[1].Type[3]
*
*   There is one final ARFONT structure which has no linked lists atttached,
*    but has a blank HDC as padding on the far right of the window.
*
*   The pointer to the array of ARFONT structures is stored in the
*    GWL_PARFONTS extra bytes for each window.  The number of face names
*    for each window is stored in the GWLU_NFACES extra bytes.
