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

4963 The parametric eqn for a cubic Bezier is, from PLRM:
4964 r(t) = at^3 + bt^2 + ct + r0
4965 with the control points:
4966 r1 = r0 + c/3
4967 r2 = r1 + (c + b)/3
4968 r3 = r0 + c + b + a

4975 r2 = 2/3 p1 + 1/3 p2
4976 and of course r0 = p0, r3 = p2
