* vfont support: Add support for converting variable-size fonts directly to
	and from vfont, bypassing PSF: fnt2vfont, vfont2fnt, vfont2bdf

* psfdiff (outputting to ppm)

* We have a psf2bsd. Can we have a bsd2psf?
  [Probably not; the BSD headers use arithmetic. Only way would be to
  have some horrible pass-to-C-compiler trick.]

* Test CP2 loading for the new-format CP2 files.
* Test 8x16 self-loading PSFs on the PCW16


* LOADPSF: Support for IBM 3270 PC Programmed Symbols board? 

[Done] * LOADPSF: ACT Apricot support (preferably in the same EXE rather than 
  having to go to the trouble of writing another).

  -- Apricot probe: The Apricot RAM BIOS at 400h should help us here. Check
    for magic at 400:4 - should be 34 12 78 56. Then 401h gives machine 
    type: 0 for PC/Xi, 1 for Portable, 2 for F-series


    The Apricot PC has fonts at 00800, 02800 and 04800 hex. The active
  font is indicated by the BIOS pointer table
	00706 = DWORD address of active font
	0070A = WORD  length of active font
	0070C = DWORD address of master font (or logo)
	00710 = WORD  length of master font (or logo)

[Done] * LOADPSF: And an F1 version.
	The F1 has the 8x8 font given by the master address, and the 8x10 font
        given by the master address + 800h. Check the length of the master 
	font, though; if it's 800h there is no 8x10 font. If it's 1200h there
	is. Probably applies to the FP version as well.
