systems.
(gamegrid-add-score-with-update-game-score): Use `cond' instead of `if'.
Provide for the case that FILE is an absolute filename. Create the directory
"$HOME/.emacs.d/games", if necessary.
(gomoku-mode): Doc fix. Add call to kill-all-local-variables,
for global-font-lock-mode.
(gomoku): Do not call gomoku-switch-to-window directly, else the
player is asked the startup questions twice after a killed game.
(gomoku-prompt-for-other-game): Throw an error if no new game,
since otherwise answering no after a killed game has no effect.
(gomoku-switch-to-window): Use gomoku-buffer-name.
(gamegrid-add-score-with-update-game-score-1): New function, factored out of
`gamegriod-add-score-with-update-game-score'.
(gamegrid-add-score-with-update-game-score): Use it. Fall back on
`gamegrid-add-score-insecure' if the requested file does not exist in
$(gamedir), in case the user has installed a game on his own.
(gamegrid-add-score-insecure): Accept optional directory argument.
(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.
