(gamegrid-xbm): new variable; XBM image as a replacement for
`gamegrid-xpm' on Emacsen compiled without XPM-support.
(gamegrid-colorize-glyph): Ported XEmacs-code for the generation
of images to Emacs.
(gamegrid-match-spec): Call `gamegrid-make-image-from-vector' to
convert XEmacs-type image descriptors.
(gamegrid-color-display-p): Removed. (Use `display-colors-p' instead.)
(gamegrid-make-image-from-vector): New function. Convert XEmacs'
image descriptors.
(gamegrid-display-type): Use Emacs' standard `display-.*-p'
functions to check for display capabilities. Fix the recognition
of image-support in Emacs 21 by this way.
(gamegrid-hide-cursor): Removed.
(gamegrid-setup-default-font): Ported the code from XEmacs to
Emacs: create a new face and assign the variable `gamegrid-face'
to it. Make sure that the face is not higher than the smallest
image used by the game.
(gamegrid-initialize-display): Use `(setq cursor-type nil)'
instead of `gamegrid-hide-cursor'.
(gamegrid-set-face): If `gamegrid-display-mode' is 'glyph, put an
image in the buffer, instead of applying a face.
(gamegrid-init-buffer): If `gamegrid-display-mode' is 'glyph, put
the face held by `gamegrid-face' in an overlay over the whole
buffer to emulate a buffer-local default-face.
Use doctor-shorten's return value.
(doctor-shorten): Compute a return value, don't alter `sent'.
(doctor-hates1): Add a question mark.
(doctor-strangelove): Unused function deleted.
(zone): Don't fiddle with the idle timer at all.
(zone-when-idle): Put the idle timer in zone-timer.
If one is already set up, cancel it and make a new one.
(zone-leave-me-alone): Likewise.
(gamegrid-add-score-insecure): Restored from the old `update-game-score'.
(gamegrid-add-score): Just dispatch on `system-type' to one of the
previous two functions.
(mpuz-trivial-face, mpuz-text-face, mpuz-solve-when-trivial)
(mpuz-allow-double-multiplicator): new options for nicer look and
new features.
(mpuz-put-number-on-board, mpuz-paint-number, mpuz-solve): new
functions.
(mpuz-check-all-solved, mpuz-random-puzzle)
(mpuz-paint-statistics, mpuz-paint-digit, mpuz-close-game)
(mpuz-show-solution): functions streamlined and removed french
style space before punctuation, added face support and optional
solving of trivial results.
(snake-final-x-velocity, snake-final-y-velocity):
New variable and functions. Store user's keypresses
into a queue and pop from the queue each subsequent turn.
(snake-update-game, snake-move-left)
(snake-move-right, snake-move-up, snake-move-down, snake-active-p)
(snake-start-game): Use that queue.
(snake-use-glyphs-flag): Renamed from snake-use-glyphs.
(snake-use-color-flag): Likewise.
(snake-mode): Rename uses of those variables.
color-capable display as color-x, if display-color-p is fboundp.
(gamegrid-make-color-x-face): Don't call gamegrid-color twice.
(gamegrid-make-color-tty-face): Use the value of color, not the
symbol itself. Don't call gamegrid-color.
(zone-hiding-modeline): New macro.
(zone-call): New func.
(zone): Init `modeline-hidden-level' symbol property.
Use `zone-call' instead of `funcall'.
(zone-pgm-whack-chars): Use `make-string' (bug introduced in 2001-10-26T20:11:25Z!monnier@iro.umontreal.ca).
(zone-pgm-stress): Use `zone-hiding-modeline'.
(zone-pgm-stress-destress): New zone program.
