ChangeLog:

2021-01-12 John Elliott

	* psftools-1.1.0 released.
	* ams2psf, psf2ams: Now support SCRCHAR.JOY, the LocoScript screen
	          font file.
	* psf2ams: A short .PSF font converted to a .COM file will now only
	          redefine those characters defined by the .PSF font.

2020-12-22 John Elliott

	* Support added for (internal and external) code page mappings
	 with more than 256 characters. The format of the .CP2 files used
	 to hold these mappings has been changed accordingly.
	* Codepage names are now matched case-insensitively.
	* New codepages: LS3 (LocoScript 3), QX10 (Epson QX-10) and PRINTIT
	 (MML Systems Printit, a subset of QX10)
	* raw2psf: Bugfix: --codepage was not setting the Unicode mapping on
		the last character in the font.
	* psf2ams: If passed an 8x16 font, the self-loading COM file now
		  loads it at full height on the PCW16 (and scales it down
		  on other computers).
	* psf2xbm: Added an --across option allowing the width of the output
	 bitmap to be changed (height is adjusted to match).
