472 * Notes on .fon files
473 *
474 * The fonts System, FixedSys and Terminal are special. There are typically multiple
475 * versions installed for different resolutions and codepages. Windows stores which one to use
476 * in HKEY_CURRENT_CONFIG\\Software\\Fonts.
477 * Key Meaning
478 * FIXEDFON.FON FixedSys
479 * FONTS.FON System
480 * OEMFONT.FON Terminal
481 * LogPixels Current dpi set by the display control panel applet
482 * (HKLM\\Software\\Microsoft\\Windows NT\\CurrentVersion\\FontDPI
483 * also has a LogPixels value that appears to mirror this)
484 *
485 * On my system these values have data: vgafix.fon, vgasys.fon, vga850.fon and 96 respectively
486 * (vgaoem.fon would be your oemfont.fon if you have a US setup).
487 * If the resolution is changed to be >= 109dpi then the fonts goto 8514fix, 8514sys and 8514oem
488 * (not sure what's happening to the oem codepage here). 109 is nicely halfway between 96 and 120dpi,
489 * so that makes sense.
490 *
491 * Additionally Windows also loads the fonts listed in the [386enh] section of system.ini (this doesn't appear
492 * to be mapped into the registry on Windows 2000 at least).
493 * I have
494 * woafont=app850.fon
495 * ega80woa.fon=ega80850.fon
496 * ega40woa.fon=ega40850.fon
497 * cga80woa.fon=cga80850.fon
498 * cga40woa.fon=cga40850.fon
