445 * Notes on .fon files

447 * The fonts System, FixedSys and Terminal are special. There are typically multiple
448 * versions installed for different resolutions and codepages. Windows stores which one to use
449 * in HKEY_CURRENT_CONFIG\\Software\\Fonts.
450 * Key Meaning
451 * FIXEDFON.FON FixedSys
452 * FONTS.FON System
453 * OEMFONT.FON Terminal
454 * LogPixels Current dpi set by the display control panel applet
455 * (HKLM\\Software\\Microsft\\Windows NT\\CurrentVersion\\FontDPI
456 * also has a LogPixels value that appears to mirror this)
457 *
458 * On my system these values have data: vgafix.fon, vgasys.fon, vga850.fon and 96 respectively
459 * (vgaoem.fon would be your oemfont.fon if you have a US setup).
460 * If the resolution is changed to be >= 109dpi then the fonts goto 8514fix, 8514sys and 8514oem
461 * (not sure what's happening to the oem codepage here). 109 is nicely halfway between 96 and 120dpi,
462 * so that makes sense.
463 *
464 * Additionally Windows also loads the fonts listed in the [386enh] section of system.ini (this doesn't appear
465 * to be mapped into the registry on Windows 2000 at least).
466 * I have
467 * woafont=app850.fon
468 * ega80woa.fon=ega80850.fon
469 * ega40woa.fon=ega40850.fon
