This changeset also rearranges native image transform code
for other platforms to make it cleaner, and also removes
the support for native cropping. For the discussions, see
https://lists.gnu.org/archive/html/emacs-devel/2019-06/msg00242.html
* src/w32term.c (w32_image_rotations_p, transform): New functions.
(w32_draw_image_foreground): If image rotation is requested
and supported, call PlgBlt to transform the image.
(w32_initialize): Populate the PlgBlt function pointer if it
is supported.
* src/w32term.h (w32_image_rotations_p): Add prototype.
* src/dispextern.h (struct image) [HAVE_NTGUI]: New member xform.
* src/image.c (compute_image_rotation): Renamed from
image_set_rotation. Only compute and returns the rotation
angle; leave the matrix calculation for later. Log an error
message if the :rotation parameter is not a number.
(image_set_crop): Function deleted. We no longer support
native cropping, as one can display an image slice instead.
(image_set_transform): Compute the transform matrix in its
entirety here, in two variants: one for XRender and Cairo, the
other for NS and MS-Windows. call compute_image_size and
compute_image_rotation internally.
(lookup_image) [HAVE_NATIVE_TRANSFORMS]: Call only
image_set_transform. No need to pass the transform matrix to
image_set_transform.
(Fimage_transforms_p): Return a list of transform capabilities
rather than a simple boolean. Support TTY frames as well.
* src/nsimage.m (setTransform:): Don't invert the matrix, as
it is already inverted in image.c.

in the text that only ImageMagick supports cropping.
* doc/lispref/display.texi (Image Descriptors): Update the
documentation of native image transforms.

* doc/emacs/text.texi (Table Misc): Mention the new wiki and
mediawiki formats.
* lisp/emacs-lisp/rx.el (rx-regexp): Allow non-string forms.

(rx--subforms): New helper function for handling subforms, including
non-constant case.

zstd compressed tarballs and other files.
(dired-compress-file): Treat options found in
`dired-compress-file-suffixes' as arguments instead of part of the
program name.
To improve readability of strings produced by
`file-size-human-readable', add two optional arguments:
- SPACE, to provide a string (typically a space or non-breaking space)
to put between the number and unit. For compatibility, the default is
an empty string.
- UNIT, a string to use as unit. For compatibility, the default is
"B" in `iec' mode and the empty string otherwise.
Also fix a glitch with small numbers in `iec' mode which caused a
stray "i" in the result.
* lisp/files.el (file-size-human-readable):
Add optional SPACE and UNIT arguments and handle small numbers correctly.
