* lisp/image.el (image-type-from-file-name): Make obsolete.
(image-supported-file-p): New function that has a more sensible
value.
(image-type): Adjust caller.
* lisp/thumbs.el (thumbs-file-size, thumbs-show-image-num): Adjust
callers.
* lisp/mail/rmailmm.el (rmail-mime-set-bulk-data): Adjust caller
and logic.
* lisp/image/image-converter.el (image-convert-to-format): New
user format (bug#54494).
(image-convert, image-converter--convert-magick)
(image-converter--convert): Use it.
* lisp/image.el (image-type-header-regexps):
(image-type-file-name-regexps):
(image-type-auto-detectable): Add auto-detect code for heic.
* src/image.c (syms_of_image): Add heic as an image type under NS.
* src/nsimage.m (ns_can_use_native_image_api): Add heic to list of
possible image types in the native image support lookup.
* lisp/image.el (image-animate-timeout): Fix bug that caused the
local variable time-to-load-image to be practically zero, instead
of the time it actually took to load the image. I think
this bug was introduced in 2013-02-16T03:29:30Z!rgm@gnu.org.
* lisp/image.el (image-animate): Allow the animation to be stopped
automatically when the image is removed from the buffer.
(image-animate-timeout): Stop the animation if the image is
removed (and that has been requested).
* lisp/net/shr.el (shr-put-image): Stop animations if the image is
removed.
* doc/lispref/display.texi (Showing Images): Mention it.
* lisp/image.el (insert-image): Take an optional parameter to
inhibit isearch of the STRING argument.
* doc/lispref/text.texi (Special Properties): Mention it.
* lisp/image.el (insert-image): Make `C-s' skip over the image data.
* lisp/isearch.el (isearch--search-skip-inhibited): New function.
(isearch-search-string): Use it.
(isearch--invisible-p): New function.
(isearch-range-invisible): Use it.
* lisp/image.el (image-show-frame): Don't force an update if the
buffer with the animation isn't in a window (bug#47895). Also
just update the window in question.
* lisp/image.el (image-animate): Only compute the animation data
once -- this avoids recomputing the image on every iteration when
the image is not displayed (bug#47895).
These came to light in the contexts of bug#29713 and bug#47234.
* lisp/emulation/edt-mapper.el (edt-xserver):

are known to be present at runtime in GUI builds.

interactively in a non-GUI build (bug#29713).
* lisp/international/mule-diag.el (describe-font):
* lisp/org/org-macs.el (org--string-from-props): Pacify warnings
about unknown functions in non-GUI bilds.

check in non-GUI builds, to pacify unused lexical variable warning.

Declare tool-bar-map as a special variable in non-GUI builds.

(find-image--cache): New variable.
* lisp/tool-bar.el (tool-bar--image-expression): Use cached data
to avoid looking up the image files on each refresh.
* lisp/image.el (image-animate-timeout): Make the animation
auto-stop use a decaying average to determine when to stop
(bug#40685). The default stop condition will probably require
some tweaking -- the current default may be too aggressive.
* lisp/image.el (image-increase-size, image-decrease-size):
Add optional arg position.
(image-mouse-increase-size, image-mouse-decrease-size):
Use '(point-marker)' for arg position.

Add optional arg position.

image--change-size to defvar that has the value of lambda
returned from debounce-reduce. (Bug#38187)
* lisp/image.el (image-mouse-increase-size)
(image-mouse-decrease-size): New commands.
(image-map): Bind C-wheel-down and C-mouse-5 to
image-mouse-decrease-size, C-wheel-up and C-mouse-4 to
image-mouse-increase-size.
* lisp/image.el (image-type): Allow passing in the image type.
(create-image): Make conversion work with data in addition to files.
* lisp/image/image-converter.el (image-convert-p): Allow taking
working on data in addition to files (bug#38036).
(image-convert): Ditto.
(image-converter--convert): Extend signature to say whether we're
getting a file or data.
(image-converter--convert-magick): Convert data.

* lisp/files.el (auto-mode-alist): Add a bunch of image suffixes
to the list (bug#37972) based on the output from "gm convert -list
format" (i.e., graphicsmagick).
* lisp/image-mode.el (image-mode): Rewrite to possibly notify the
user about image-use-external-converter.
(image-mode--setup-mode): Factor out into own function and don't
run under `condition-case' as there's nothing here that should
error.
* lisp/image.el (unknown-image-type): New error.
(image-type): Signal that error so that image-mode can offer
sensible feedback to the user.

Doc fix; return value is the MEMBER argument, not nil.
* lisp/files.el (hack-one-local-variable-eval-safep):
* lisp/play/doctor.el (doctor-nounp, doctor-pronounp):
* lisp/progmodes/flymake-proc.el (flymake-proc--check-include):
* lisp/progmodes/js.el (js--broken-arrow-terminates-line-p):
Doc fix; a non-nil return value is not always t.
* lisp/image.el (image-type-available-p):
* lisp/simple.el (region-active-p):
* lisp/window.el (frame-root-window-p):
* src/buffer.c (Fbuffer_live_p):
* src/image.c (Finit_image_library):
