/******************************Module*Header*******************************\
* Module Name: stockfnt.cxx
*
* Initializes the stock font objects.
*
* Note:
*
* This module requires the presence of the following section in the
* WIN.INI file:
*
* [GRE_Initialize]
* fonts.fon=[System font filename]
* oemfont.fon=[OEM (terminal) font filename]
* fixedfon.fon=[System fixed-pitch font filename]
*
* Also, an undocumented feature of WIN 3.0/3.1 is supported: the ability
* to override the fonts.fon definition of the system font. This is
* done by defining SystemFont and SystemFontSize in the [windows]
* section of WIN.INI.
*
*
* Rewritten 13-Nov-1994 Andre Vachon [andreva]
* Created: 06-May-1991 11:22:23
* Author: Gilman Wong [gilmanw]

* hfontInitDefaultGuiFont
*
* Initialize the DEFAULT_GUI_FONT stock font.
*
* The code Win95 uses to initialize this stock font can be found in
* win\core\gdi\gdiinit.asm in the function InitGuiFonts. Basically,
* a description of several key parameters (height, weight, italics,
* charset, and facename) are specified as string resources of GDI.DLL.
* After scaling, to compensate for the DPI of the display, these parameters
* are used to create the logfont.
*
* We will emulate this behavior by loading these properties from the
* registry. Also, so as to not have to recreate the hives initially, if
* the appropriate registry entries do not exist, we will supply defaults
* that match the values currently used by the initial Win95 US release.
*
* The registry entries are:
*
* [GRE_Initialize]
* ...
*
* GUIFont.Height = (height in POINTS, default 8pt.)
* GUIFont.Weight = (font weight, default FW_NORMAL (400))
* GUIFont.Italic = (1 if italicized, default 0)
* GUIFont.CharSet = (charset, default ANSI_CHARSET (0))
* GUIFont.Facename = (facename, default "MS Sans Serif")
*
* Note: On Win95, the facename is NULL. This defaults to "MS Sans Serif"
* on Win95. Unfortunately, the WinNT mapper is different and will
* map to "Arial". To keep ensure that GetObject returns a LOGFONT
* equivalent to Win95, we could create this font as LF_FLAG_ALIASED
* so that externally the facename would be NULL but internally we
* use one with the appropriate facename. On the other hand, an app
* might query to find out the facename of the DEFAULT_GUI_FONT and
* create a new font. On Win95, this would also map to "MS Sans Serif",
* but we would map to "Arial". For now, I propose that we go with
* the simpler method (do not set LF_FLAG_ALIASED). I just wanted
* to note this in case a bug arises later.
