/****************************************
* Notes on .fon files
*
* The fonts System, FixedSys and Terminal are special. There are typically multiple
* versions installed for different resolutions and codepages. Windows stores which one to use
* in HKEY_CURRENT_CONFIG\\Software\\Fonts.
* Key Meaning
* FIXEDFON.FON FixedSys
* FONTS.FON System
* OEMFONT.FON Termial
* LogPixels Current dpi set by the display control panel applet
* (HKLM\\Software\\Microsft\\Windows NT\\CurrentVersion\\FontDPI
* also has a LogPixels value that appears to mirror this)
*
* On my system these values have data: vgafix.fon, vgasys.fon, vga850.fon and 96 respectively
* (vgaoem.fon would be your oemfont.fon if you have a US setup).
* If the resolution is changed to be >= 109dpi then the fonts goto 8514fix, 8514sys and 8514oem
* (not sure what's happening to the oem codepage here). 109 is nicely halfway between 96 and 120dpi,
* so that makes sense.
*
* Additionally Windows also loads the fonts listed in the [386enh] section of system.ini (this doesn't appear
* to be mapped into the registry on Windows 2000 at least).
* I have
* woafont=app850.fon
* ega80woa.fon=ega80850.fon
* ega40woa.fon=ega40850.fon
* cga80woa.fon=cga80850.fon
* cga40woa.fon=cga40850.fon
