* 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/frame.el (frame-notice-user-settings): Declare functions that
are known to be present at runtime in GUI builds.
(make-frame-on-display): Signal more informative error when called
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.
* lisp/mh-e/mh-mime.el (mh-small-image-p): Avoid eliminating fboundp
check in non-GUI builds, to pacify unused lexical variable warning.
* lisp/net/newst-plainview.el (newsticker--plainview-tool-bar-map):
* lisp/net/newst-treeview.el (newsticker-treeview-tool-bar-map):
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.

Use funcall to call image--change-size-function.

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.

getting a file or 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.
* lisp/progmodes/flymake-proc.el (flymake-proc--find-buffer-for-file):
Doc fix; return value is a buffer, not t.

(HAVE_NATIVE_SCALING, HAVE_NATIVE_TRANSFORMS): Rename and change all
relevant locations.
* src/image.c (x_set_image_rotation):
(x_set_transform): New functions.
(x_set_image_size): Use transform matrix for resizing under X and NS.

(Fimage_scaling_p, Fimage_transforms_p): Rename and update all
callers.

definitions.
* src/nsterm.m (ns_dumpglyphs_image): Use the transform to draw the
image correctly.
* src/xterm.c (x_composite_image): Use PictOpSrc as we don't care
about alpha values here.

(ImageMagick Images): Remove :rotation.
Restore lines saying "Maintainer: emacs-devel@gnu.org" when there is
no special maintainer for a file. Although this wasn't documented
it was common practice and removing the lines didn't have consensus.
Prefer librsvg for display of splash.svg
When both librsvg and Imagemagick are available, Emacs should
prefer librsvg to render SVG images. However, Emacs was using
Imagemagick to render its own splash.svg file because
image-type-from-file-header returned nil for that file.
* lisp/image.el (image-type-from-buffer)
(image-type-from-file-header): Look at the first 8192 bytes of
the image, not just the first 256. For Emacs’s own splash.svg
file, image-type-header-regexps needs to look at 939 bytes.
8192 bytes is a reasonable number nowadays given typical file
system design.
* test/lisp/image-tests.el (image-tests--emacs-images-directory):
New contant.
(image-type-from-file-header-test): New test.
