function.  Call c-do-brace-electrics for the inserted brace, and perhaps for a
brace inserted by electric-pair-self-insert-function.

C, Emacs Lisp, and Texinfo, as the Emacs codebase doesn't use them.

Without this patch, it was theoretically possible for a list
length to be a bignum, which means that safe-length could
signal an error (due to generating a too-large bignum) contrary
to its documentation.  Fix things to remove the theoretical
possibility, so that list lengths are always fixnums (and so
that list lenghts are always ptrdiff_t values too, since that
is assumed internally anyway).
* src/alloc.c (Fcons): Do not allocate so many conses that
a list length won’t fit into ptrdiff_t or into fixnum.
This matters only on weird platforms; on typical platforms,
list lengths always fit anyway.
* src/fns.c (list_length, Fsafe_length, proper-list-p):
Remove integer overflow checks that are no longer needed.

This mostly just reindents.
* src/image.c (x_set_image_size): Always define, but to a no-op
if !HAVE_NATIVE_SCALING, to avoid an #ifdef elsewhere.

* src/xterm.c (x_composite_image): Avoid ‘else #endif’.

* src/Makefile.in (XRENDER_LIBS): List XRender libs separately from
xft libs.
* lisp/image.el (image--get-imagemagick-and-warn): Allow resizing if
native scaling is available.
* src/dispextern.h: Add XRender and image scaling stuff.
(struct image): Add XRender Pictures.
* src/image.c (x_create_bitmap_mask):
(image_create_x_image_and_pixmap): Handle XRender Picture.
(scale_image_size):
(compute_image_size): Make available when any form of scaling is
enabled.
(x_set_image_size): New function.
(lookup_image): Set image size.
(x_create_x_image_and_pixmap): Create XRender Picture when necessary.
(x_put_x_image): Handle the case where desired size != actual size.

(x_draw_image_foreground): Use new x_composite_image function.
* doc/lispref/display.texi (Image Descriptors): Document
image-scaling-p and add resizing descriptors.

New file.

doc-string.
(window--display-buffer): Remove fifth argument DEDICATED and
either directly use a 'dedicated' entry in ALIST or the value
of 'display-buffer-mark-dedicated' instead.

implementation.  (Bug#28705)
Copyright-paperwork-exempt: yes.

When calculating the length of a Lisp object whose type is
known, use a specialized length operation on it to save a bit
of runtime overhead.
