Checking for charset *known* to be EQ to the SLUG charset, didn't verify that the font *had* a SLUG charset, so was comparing to NIL, which excluded *all* unloaded charsets.
* Upgrade Sketch to new font interfaces
* Tedit changes so that TEDIT.GETSYNTAX conforms to documentation
* Remove RUBOUT interrupt
* TEDIT-FNKEYS: uses keywords for action names
* LLKEY: Change keybindings for DELETE and LOOKS
* SEDIT-COMMANDS: Shift-DELELETE is wordelete.backwards
* Sketch implements arrow keys
I'm not sure what I did wrong with PR #2396 but it didn't revert
lispusers/BACKGROUND-YIELD(.LCOM).
I did what I thought was the same process, but it seems to have picked
up the right files this time.
Removed WRITE-BDF-TO-DISPLAYFONT-FILE (i.e., no STRIKE format files).
No multiple-values returned. Instead, use LIST when appropriate.
BDF-TO-CHARSETINFO is now IDEMPOTENT w.r.t. the GLYPHS.
Move resolution and defaulting of FAMILY, FACE, SIZE, ROTATION, DEVICE from WRITE-BDF-TO-MEDLEYDISPLAYFONT-FILE to BDF-TO-FONTDESCRIPTOR.
Keep the MCCS chars present BITMAP in the BDF-FONT structure, instead of needing to schlepping it around separately.
Abstracted testing/setting the MCCS chars present bits to CHAR-PRESENT-BIT (mimicking BITMAPBIT).
Added COUNT-MCHARS to know how many MCCS chars are marked in the BITMAP as present.
READ-BDF now handles when UTOMCODE? returns multiple mappings, and creates the appropriate duplicate GLYPHS with different MCCS char codes.
READ-GLYPH doesn't create an empty BITMAP for spacing glyphs.
Use font code changes:
Set (CHARSETINFO CHARSETNO).
Set (FONTDESCRIPTOR FONTSLUGWIDTH).
* loadup scripts: set MEDLEY-INIT-VARS to NOBIND before loading MEDLEYDIR
so that INITVARS in MEDLEYDIR replaces any previous settings in the loadup-sysout
* FONT: add cache for FONTSAVAILABLE, add FLUSHFONTCACHE. See FONTCODECHANGES.tedit
* Make FONTEXISTS and FONTSAVAILABLE consistent
* Add BACKGROUND-YIELD to Lisp.sysout (and thus to FULL.SYSOUT) so you don't need to load it in INITs.
* remove CAUSE-INTERRUPT subr call; doesn't add value
* Verbose mode (READ-BDF) was implemented incorrectly - fixed
* Cleanup DEFPACKAGE in source file using :IMPORT-FROM, and fewer imports.
* Various renaming for consistency with XCCS -> MCCS changes.
* Use IL:FONTSPEC record instead of using FIRST, SECOND, etc.
* Fix the parsing of IL:FONTSPEC to use COMPRESSED instead of incorrect CONDENSED.
* Zero-width "image" with zero-width "escapement" GLYPHS now get put into NOMAPPINGCHARSET.
* Add (FILES (SYSLOAD) SYSEDIT) under existing (DECLARE: EVAL@COMPILE DONTCOPY ...)
