479 * Notes on .fon files
480 *
481 * The fonts System, FixedSys and Terminal are special. There are typically multiple
482 * versions installed for different resolutions and codepages. Windows stores which one to use
483 * in HKEY_CURRENT_CONFIG\\Software\\Fonts.
484 * Key Meaning
485 * FIXEDFON.FON FixedSys
486 * FONTS.FON System
487 * OEMFONT.FON Terminal
488 * LogPixels Current dpi set by the display control panel applet
489 * (HKLM\\Software\\Microsoft\\Windows NT\\CurrentVersion\\FontDPI
490 * also has a LogPixels value that appears to mirror this)
491 *
492 * On my system these values have data: vgafix.fon, vgasys.fon, vga850.fon and 96 respectively
493 * (vgaoem.fon would be your oemfont.fon if you have a US setup).
494 * If the resolution is changed to be >= 109dpi then the fonts goto 8514fix, 8514sys and 8514oem
495 * (not sure what's happening to the oem codepage here). 109 is nicely halfway between 96 and 120dpi,
496 * so that makes sense.
497 *
498 * Additionally Windows also loads the fonts listed in the [386enh] section of system.ini (this doesn't appear
499 * to be mapped into the registry on Windows 2000 at least).
500 * I have
501 * woafont=app850.fon
502 * ega80woa.fon=ega80850.fon
503 * ega40woa.fon=ega40850.fon
504 * cga80woa.fon=cga80850.fon
505 * cga40woa.fon=cga40850.fon
