* etc/NEWS: Document timer format change.
* lisp/image.el (image-animate-timer):
* lisp/time.el (display-time-world-timer):
Use timer--function and timer--args rather than raw access to
timer vector.
* lisp/gnus/gnus-art.el (gnus-article-stop-animations):
Use timer--function rather than raw access to timer vector.
Fixes: debbugs:12430
* lisp/image.el (imagemagick-enabled-types): Rename from
imagemagick-types-enable. Add many more types.
(imagemagick-types-inhibit): Change default to nil.
(imagemagick-filter-types): Caller changed.
* lisp/image.el: For clarity, call imagemagick-register-types at
top-level, rather than relying on a custom :initialize.
(imagemagick-types-enable): New option.
(imagemagick-register-types): Respect imagemagick-types-inhibit.
If disabling support, remove elements altogether rather
than using an impossible regexp.
(imagemagick-types-inhibit): Give it the default init function.
* src/image.c (Fimagemagick_types): Doc fix.
* etc/NEWS: Mention this.
Fixes: debbugs:11557
* lisp/image.el (imagemagick--extension-regexp): New variable.
(imagemagick-register-types): Use it.
(imagemagick-types-inhibit): Add :set function. Allow new value
of t to inhibit all types.
* lisp/loadup.el (fboundp): Preload regexp-opt, needed by
imagemagick-register-types.
* lisp/emacs-lisp/regexp-opt.el (regexp-opt-charset): Avoid cl macros,
so we can preload it.
* image.el (put-image): Return the overlay created instead of the
optional input string. Note that this may break code
that is (for some reason or other) depending on `put-image'
returning the string.
Fixes: debbugs:7834
* lisp/image.el (image-animated-p): Return animation delay in seconds.
Avoid bit manipulation in Lisp; use `delay' entry in the metadata.
(image-animate-timeout): Remove DELAY argument. Use
image-animated-p to get animation delay for each frame.
(image-animate): Caller changed.
* src/image.c (gif_load): Add animation frame delay to the metadata.
(syms_of_image): Use DEFSYM. New symbol `delay'.
* lisp/image.el (image-animate-max-time): Moved to image-mode.el.
(create-animated-image): Remove unnecessary function.
(image-animate): Rename from image-animate-start. New arg.
(image-animate-stop): Removed; just use image-animate-timer.
(image-animate-timer): Use car-safe.
(image-animate-timeout): Rename argument.
* lisp/image-mode.el (image-toggle-animation): New command.
(image-mode-map): Bind it to RET.
(image-mode): Update message.
(image-toggle-display-image): Avoid a spurious cache flush.
(image-transform-rotation): Doc fix.
(image-transform-properties): Return quickly in the normal case.
(image-animate-loop): Rename from image-animate-max-time.
* lisp/image-mode.el (image-toggle-display-image): Ensure that the
image spec passed to the animate timer is the same object as in
the the buffer's display property.
(image-transform-properties): Doc fix.
* lisp/image.el (image-animate-max-time): Default to nil.
* lisp/image.el (image-animate-max-time): Allow nil and t values.
Default to nil.
(create-animated-image): Doc fix.
(image-animate-start): Remove second arg; just use
image-animate-max-time.
(image-animate-timeout): Doc fix. Args changed.
* image.el (image-type-file-name-regexps): Make it variable.
`imagemagick-register-types' modifies it, and the user may want
to add new extensions for known image types.
(imagemagick-register-types): Throw error if not using ImageMagick.
* cus-edit.el (custom-face-edit-fix-value): Use
custom-fix-face-spec.
* custom.el (custom-push-theme): Cleanup (use cond).
(disable-theme): Recompute the saved-face property.
(custom-theme-recalc-face): Follow face alias before setting prop.
* custom.el (custom-fix-face-spec): New function; code moved from
custom-face-edit-fix-value.
(custom-push-theme): Use it when checking if a face has been
changed outside customize.
(custom-available-themes): New function.
(load-theme): Use it.
* image.el (image-checkbox-checked, image-checkbox-unchecked): New
variables, containing checkbox images.
* startup.el (fancy-startup-tail):
* wid-edit.el (checkbox): Use them.
